Suppression of ferromagnetism in van der Waals insulator due to pressure-induced layer stacking variation
M. Misek, U. Dutta, P. Kral +15
Ferromagnetism in van der Waals insulators like CrBr3 is highly sensitive to structural modifications. We explore the pressure-driven structural and magnetic transformations of the…
Magnetic ordering in VI3: a van der Waals material combining vastly different magnetic anisotropies
K. K. Pokhrel, S. Ray, N. Machavcova +2
Among magnetic van der Waals materials, the vanadium trihalide family exhibits unique features. In particular, VI3 contains V atoms of two different types, as two energetically clo…
Opposite pressure effects on magnetic phase transitions in NiBr2
Parvez Ahmed Qureshi, Krishna Kumar Pokhrel, Jiri Prchal +5
NiI2 and NiBr2 are archetypal van der Waals (vdW) triangular-lattice multiferroics that host incommensurate helimagnetic order at the lowest temperatures and undergo a transition t…
Direct ab initio calculation of magnons in altermagnets: method, spin-space symmetry aspects, and application to MnTe
L. M. Sandratskii, K. Carva, V. M. Silkin
We suggest the method for direct ab initio calculation of magnons in complex collinear magnets. The method is based on the density-functional-theory calculation under two different…
Unique magnetic structure of the vdW antiferromagnet VBr
Milan Klicpera, Ondrej Michal, David Hovancik +5
VBr is a van der Waals antiferromagnet below the Néel temperature of 26.5 K with a saturation moment of 1.2 mB/f.u. above the metamagnetic transitions detected in the in-plane…
