Agne CiuciulkaiteAgne Ciuciulkaite

Uppsala University (Uppsala, Sweden)

My PhD project is entitled “Interaction of light with magnetic structures”. The questions and tasks raised in this project are of a fundamental science interest and address the light-magnetism interaction in various magnetic and optic materials and nanostructures. The PhD research project is based on the experimental work in fabrication and characterization of magnetoplasmonic materials, thin films and arrays. My goal is to investigate the light and magnetism interaction with the help of optical and magneto-optical methods. Also, to investigate the light induced magnetization dynamics and carry out research on how light can modify magnetization and vice versa.

Dr. Sergii Parchenko

Paul Scherrer Institute / Swiss Light Source (Villigen, Switzerland)
Sergii Parchenko’s research interest mainly focused on study the behavior of magnetic and strongly correlated systems after excitation with short and intense laser light. In particular, how to use light to change the state of the material on the ultrafast time scale, understanding of the processes, which take place during this process.
Sergii Parchenko finished his Master course in Applied Physics at Donetsk National University in 2012. For his PhD, he was studying at University of Bialystok in Poland. During the PhD, he was involved in studies of ultrafast spin dynamics in ferrimagnets focused on understanding of inter-sublattice exchange interaction between rare earth and transition metal ions on the ultrafast time scale (as a primary topic) and study of magneto-plasmonic effect (as a secondary topic). After graduation in 2016, Sergii moved to Switzerland and, as a PostDoc, joined the Microscopy and Magnetism group at PSI lead by Dr. Urs Staub where he is currently located. Here in PSI, he was involved in studies of ultrafast dynamics in strongly correlated materials mostly using soft X-ray spectroscopy and scattering techniques (both elastic and inelastic scattering) with aim to clarify the electronic, spin and structural properties of strongly correlated materials on the ultrafast time scale and interactions between them after the excitation with fs NIR-visible and THz radiation. Since July, 2018, he has been invited to join the “FEMTOTERABYTE” project in frame of Horizon 2020 framework program focused on study the possibility of all optical switching of the magnetization in nanostructures using the plasmonic effects.

Ms. Gaia Petrucci

University of Pisa (Pisa, Italy)
Gaia Petrussi's PhD project involves functionalizing plasmonic nanostructured surfaces using magnetic nanoparticles for high-density data storage.

Abstract

Through magnetoplasmonics, the combination of magnetic and plasmonic materials, one can exploit the interplay of light and magnetism to envisage technological applications like all-optical magnetic switching, leading to the realization of densely packed and fast switchable bits. The approach that we chose to pursuit toward this aim is to functionalize plasmonic nanoantennas with magnetic metal oxides nanoparticles, in order to study how these two elements interact. The plasmonic nanoantennas are gold nanostructures evaporated on glass surfaces. These nanostructured surfaces are realized by Goteborg University through soft lithographic techniques (i.e. hole-mask colloidal lithography using polystyrene nanospheres). In this way it is possible to obtain non-interacting nanoantennas supporting Localized Surface Plasmons Resonance (LSPR), the collective oscillation of free electrons confined in a metal nanostructure. This kind of nanostructures are able to collect external light and to concentrate the electric field carried by it in some specific hot-spots. By arranging the magnetic nanoparticles in these hot-spots we aim at tailoring light-matter interactions at the nanoscale.

PhD project

My PhD project involves the synthesis, characterization and evaluation of magneto-optical properties of magnetoplasmonic nanoparticles.
The modulation of the optical response of plasmonic nanoparticles (NPs) by means of an external magnetic field, i.e. magnetoplasmonics, can trigger interesting innovations in the design of optical switches, modulators or more efficient refractometric sensors [1,2]. The enhancement of this magnetic modulation is a challenging goal in magnetoplasmonics. A previous works proved the ability of Magnetic Circular Dichroism (MCD) to detect small magnetic field-induced energy shifts of the plasmonic modes in simple Au NPs, which were modelled in terms of simple equations of motion of free electrons [3,4]. Nevertheless, the MCD signal of Au NPs is small and it can be further enhanced through the design and preparation of new magnetoplasmonic NPs with large magneto-optical signal. In my PhD project I am exploiting two main strategies to this purpose, which involve different kind of nanostructured materials. These materials are synthesized by colloidal chemistry approaches, and characterized structurally, magnetically, optically and magneto-optically.
The first approach is the preparation of hybridized magnetoplasmonic NPs, by alloying Au with magnetic metals (Fe, Co or Ni) and exploiting the magnetic interaction between the conduction electrons of Au and the spin polarized electrons of magnetic metals to increase the magnetic modulation. Different composition of the NPs are evaluated, in order to introduce magnetic properties without damping the plasmonic resonance and find the right balance between plasmonic and magnetic properties.
The second approach consists in the use of heavily doped semiconductors. Among these class of plasmonic materials, n-doped Indium-Tin-Oxide (n-ITO) NPs display a sharp plasmonic absorption in the Near-Infrared region of the spectrum [5,6]. Thanks to the low LSPR peak width and to the lower electron effective mass of n-ITO with respect to Au, the magnetic modulation of surface plasmons in n-ITO NPs is at least one order of magnitude higher than in simple Au NPs. By tuning synthetic parameters we are trying to modulate the structural parameters of n-ITO NPs, aiming at improving the magnetoplasmonic properties.
