Cubic-in-magnetization contributions to the magneto-optic Kerr effect investigated for Ni(001) and Ni(111) thin films
Robin Silber, Maik Gaerner, Kamil Postava +2
*The abstract of this article is too long to be included in the arXiv metadata; please see the paper for the full abstract.* ...In this paper, we introduce the detailed theory of c…
Atomic Layer-controlled Nonlinear Terahertz Valleytronics in Dirac Semi-metal and Semiconductor PtSe2
Minoosh Hemmat, Sabrine Ayari, Martin Micica +16
Platinum diselenide (PtSe2) is a promising two-dimensional (2D) material for the terahertz (THz) range as, unlike other transition metal dichalcogenides (TMDs), its bandgap can be…
360° polarization control of terahertz spintronic emitters using uniaxial FeCo/TbCo2/FeCo trilayers
Pierre Koleják, Geoffrey Lezier, Kamil Postava +3
Polarization control of THz light is of paramount interest for the numerous applications offered in this frequency range. Recent developments in THz spintronic emitters allow for a…
Magneto-optical properties of InSb for terahertz applications
Jan Chochol, Kamil Postava, Michael Čada +5
Magneto-optical permittivity tensor spectra of undoped InSb, n-doped and p-doped InSb crystals were determined using the terahertz time-domain spectroscopy (THz-TDS) and the Fourie…
Quadratic-in-magnetization permittivity and conductivity tensor in cubic crystals
Jana Hamrlová, Jaroslav Hamrle, Kamil Postava +1
We present diagonal and off-diagonal elements of the permittivity and conductivity tensor up to the second order in magnetization for cubic crystals. We express all tensor elements…
Unidirectional band gaps in uniformly magnetized two-dimensional magnetophotonic crystals
Mathias Vanwolleghem, Xavier Checoury, Wojciech Śmigaj +6
By exploiting the concepts of magnetic group theory we show how unidirectional behavior can be obtained in two-dimensional magneto-photonic crystals (MOPhC) with uniform magnetizat…
Huge quadratic magneto-optical Kerr effect and magnetization reversal in the CoFeSi Heusler compound
J. Hamrle, S. Blomeier, O. Gaier +5
CoFeSi(100) films with L2 structure deposited onto MgO(100) were studied exploiting both longitudinal (LMOKE) and quadratic (QMOKE) magneto-optical Kerr effect. The films e…
Ion beam induced modification of exchange interaction and spin-orbit coupling in the CoFeSi Heusler compound
J. Hamrle, S. Blomeier, O. Gaier +8
A CoFeSi (CFS) film with L2 structure was irradiated with different fluences of 30 keV Ga ions. Structural modifications were subsequently studied using the longitudina…
