Abstract

Thermodynamic characteristics of a group of Heisenberg-type crystals CuM2X4 · 2H2O (where M stands for K, Rb, NH4, and X for Cl or Br) are simulated by the Monte-Carlo method (the Metropolis scheme). A comparison of calculated and experimental results makes it possible to obtain the pressure dependences of the exchange constants for nearest magnetic coordination spheres. The complex competing nature of interactions, which is manifested with increasing pressure, is confirmed.
