Electronic properties of the epitaxial thin films of a kagome ferromagnet Fe3Sn2

14:00
Zoom platform seminar Institute of Physics P.A.S.
Quantum materials with a kagome lattice structure are a promising platform for condensed matter research due to their peculiar topological, electronic, and magnetic properties. Fe3Sn2 is an intermetallic compound where kagome layers of Fe3Sn and 2D honeycomb Sn layers (stanene) are stacked on top of each other in the layered fashion. The experimental electronic structure studies of the bulk single crystals of Fe3Sn2 revealed existence of massive Dirac fermions [1] and not obvious signatures of the flat bands [2]. During the talk, I will present the results of our investigations of the electronic band structure of the thin films of Fe3Sn2. The films were grown by molecular beam epitaxy on Pt(111) and characterized using a multi-technique approach, including x-ray photoemission spectroscopy (XPS), x-ray diffraction (XRD), scanning tunneling microscopy (STM) and conversion electron Mössbauer spectroscopy (CEMS). The electronic band structure was measured using angle-resolved photoemission (ARPES) at the Phelix end station of the Solaris synchrotron in Krakow. I will present

Condensed Matter Physics Seminar
Unveils the mechanical stimuli by mechanoluminescence: From designing of experimental setups to material analysis.

14:00
Institute of Physics P.A.S. Zoom-transmitted seminar
This study provides a comprehensive analysis of mechanoluminescence (ML) and associated phenomena, ultrasonic-induced luminescence (Us-L). The research begins with the designing of various experimental techniques and setups to study ML and Us-L under diverse mechanical stimuli. The first two setups are directly related to ML analysis, namely Impact-induced ML and Stress-induced ML setups. The third setup focus on the study of Us-L at 20 kHz, utilizing an ultrasonic probe sonicator and a photomultiplier to capture Us-L emissions. The results obtained from multiple measurements of commercially available phosphor materials, includes Sr0.95Ca0.05(SO4):Mn, CaAl2O4:Eu,Dy,La and SrAl2O4:Eu,Dy validate the excellent performance of these setups in various categories of ML studies. In the second part of the study, the mechanoluminescence and ultrasonic-induced luminescence properties of LiTaO3:Pr materials are discussed in detail. The LiTaO3 used as a host material have trigonal R3c structure and praseodymium (Pr) activator
