Chirality-resolved spectroscopy of Caroli-de Gennes-Matricon states in multiband FeTeSe superconductors
T. Rõõm, A. Glezer Moshe, R. Nagarajan +4
We employ terahertz Faraday magneto-optical spectroscopy to probe the relaxation dynamics of quantized helical Caroli-de Gennes-Matricon (CdGM) states in epitaxial FeTeSe$_…
Modified Martin-Puplett interferometer for magneto-optical Kerr effect measurements at sub-THz frequencies
A. Glezer Moshe, R. Nagarajan, U. Nagel +2
We present magneto-optical Kerr effect (MOKE) spectrometer based on a modified Martin-Puplett interferometer, utilizing continuous wave sub-THz low-power radiation in broad frequen…
THz spin-wave excitations in the transverse conical phase of BiFeO
B. Tóth, D. G. Farkas, K. Amelin +7
Although BiFeO is one of the most studied multiferroic materials, recent magnetization and neutron scattering studies have revealed a new magnetic phase in this compound - the…
Magnetic field-induced phases and spin Hamiltonian in Cs2CoBr4
L. Facheris, S. D. Nabi, K. Yu. Povarov +12
Magnetic structures and spin excitations are studied across the phase diagram of the geometrically frustrated S = 3/2 quantum antiferromagnet Cs2CoBr4 in magnetic fields applied al…
