Low-energy excitations and magnetic anisotropy of the layered van der Waals antiferromagnet NiPS
K. Mehlawat, A. Alfonsov, S. Selter +4
The quasi-two-dimensional antiferromagnet NiPS belongs to the family of magnetic van der Waals compounds that provides a rich material base for the realization of funda…
Magnetic field tuning of the spin dynamics in the magnetic topological insulators (MnBiTe)(BiTe)
A. Alfonsov, K. Mehlawat, A. Zeugner +3
We report a high frequency/high magnetic field electron spin resonance (HF-ESR) spectroscopy study in the sub-THz frequency domain of the two representatives of the family of magne…
Frustration enhanced by Kitaev exchange in a triangular antiferromagnet
C. Wellm, W. Roscher, J. Zeisner +9
Triangular Heisenberg antiferromagnets are prototypes of geometric frustration, even if for nearest-neighbor interactions quantum fluctuations are not usually strong enough to dest…
Strongly anisotropic spin dynamics in magnetic topological insulators
A. Alfonsov, J. I. Facio, K. Mehlawat +8
The recent discovery of magnetic topological insulators has opened new avenues to explore exotic states of matter that can emerge from the interplay between topological electronic…
Pressure control of the magnetic anisotropy of the quasi-two-dimensional van der Waals ferromagnet CrGeTe
T. Sakurai, B. Rubrecht, L. T. Corredor +10
We report the results of the pressure-dependent measurements of the static magnetization and of the ferromagnetic resonance (FMR) of CrGeTe to address the properties of…
