Thermodynamic properties of LiCuO multiferroic compound
arXiv:1312.0293 · doi:10.1016/j.physleta.2014.03.025
Abstract
A spin model of quasi-one dimensional LiCuO compound with ground state of ellipsoidal helical structure in which the helical axis is along the diagonal of CuO squares has been adopted. By taking into account the interchain coupling and exchange anisotropy, the exotic magnetic properties and ferroelectricity induced by spiral spin order have been studied by performing Monte Carlo simulation. The simulation results qualitatively reproduce the main characters of ferroelectric and magnetic behaviors of LiCuO compound and confirm the low-temperature incollinear spiral ordering. Furthermore, by performing the calculations of spin structure factor, we systematically investigate the effects of different exchange coupling on the lower-temperature magnetic transition, and find that the spiral spin order depends not only on the ratio of nearest and next-nearest neighbor inchain spin coupling but also strongly on the exchange anisotropy.
