Anomalous Electrical Transport in the Kagome Magnet YbFe6_6Ge6_6

This study demonstrates that in the kagome magnet YbFe6_6Ge6_6, interactions between Fe and Yb moments induce a spin reorientation at low temperatures that closes the spin anisotropy gap and generates dynamic scalar spin chirality, resulting in an anomalous Hall effect despite the material's collinear antiferromagnetic order.

Opposite pressure effects on magnetic phase transitions in NiBr2

This study reveals that hydrostatic pressure exerts opposite effects on the magnetic phases of NiBr2 compared to NiI2, where pressure suppresses the helimagnetic order while steeply enhancing the collinear antiferromagnetic order due to the dominant role of interlayer exchange interactions.

Signatures of three-state Potts nematicity in spin excitations of the van der Waals antiferromagnet FePSe3_3

Neutron scattering experiments on the van der Waals antiferromagnet FePSe3_3 under uniaxial strain reveal that tensile strain induces a transition to C2C_2 symmetry in both magnetic order and spin excitations, providing direct evidence that the observed three-state Potts nematicity in the paramagnetic phase arises from vestigial order associated with the low-temperature zigzag antiferromagnetic state.
