Thermodynamics of Antiferromagnetic Solids in Magnetic Fields
arXiv:1907.11480 · doi:10.1016/j.aop.2020.168168
Abstract
We analyze the thermodynamic properties of antiferromagnetic solids subjected to a combination of mutually orthogonal uniform magnetic and staggered fields. Low-temperature series for the pressure, order parameter and magnetization up to two-loop order in the effective expansion are established. We evaluate the self-energy and the dispersion relation of the dressed magnons in order to discuss the impact of spin-wave interactions on thermodynamic observables.
