Intersite spin nematic ordering in spin chain materials: Behavior of observables

Year: 2025

Type: article

Abstract: We consider the spin-1/2 chain material. It was predicted earlier that the intersite spin nematic order can be realized due to the spin-elastic coupling in such a system. Here we show that intersite spin nematic ordered states can be studied using magnetoelastic and magnetoelectric experiments. Intersite spin nematic phases and phase transitions in spin chain materials can be observed in relative changes of the velocity of sound (related to the changes of the elastic modulus of the crystal), the magnetostriction, and, for noncenter-symmetric systems, the electric permittivity as functions of the temperature and the external magnetic field, since those relative changes are proportional to the spin quadrupole (spin nematic) susceptibility of the system.
