Uniaxial pressure applied to α-SrCr₂O₄ shifts two-magnon Raman excitations in a manner consistent with decreased or increased magnetic anisotropy under tension or compression.
SSD-based finite-size calculations show shoulder or double-peak specific heat in triangular and kagome antiferromagnets plus strong low-T susceptibility enhancement in kagome, indicating magnetic states dominate its excitations below 0.5J unlike the triangular case.
