Room-temperature antiferromagnetic resonance in NaMnAs
Jan Dzian, StáÅa Tázlarů, Ivan Mohelský +16
We report on antiferromagnetic resonance experiments in bulk tetragonal NaMnAs -- a room-temperature antiferromagnetic semiconductor. Our results corroborate previous ab initio stu…
Non-Relativistic Anisotropic Magnetoresistance with Collinear and Non-Collinear Magnetic Order
Philipp Ritzinger, OndÅej SedláÄek, Jakub Železný +1
Anisotropic magnetoresistance (AMR) arises from symmetry lowering of the conductivity tensor induced by magnetic order. In simple ferromagnets, AMR is a relativistic effect, relyin…
Antiferromagnetic resonance in -MnTe
J. Dzian, P. KubaÅ¡ÄÃk, S. Tázlarů +20
Antiferromagnetic resonance in a bulk -MnTe crystal is investigated using both frequency-domain and time-domain THz spectroscopy techniques. At low temperatures, an excitation…
Quench switching of Mn2As
Kamil OlejnÃk, ZdenÄk KaÅ¡par, Jan ZubÃ¡Ä +10
We demonstrate that epitaxial thin film antiferromagnet Mn2As exhibits the quench-switching effect, which was previously reported only in crystallographically similar antiferromagn…
