Theory of liquid magnets

A study is made of the thermodynamic correlation, magnetic and structure functions of the model of a liquid magnet whose basic Hamiltonian contains not only typical interparticle interactions in a liquid but also spin-spin interactions of Heisenberg type. The magnetic and liquid equations of state are found. The critical temperatures of the magnetic phase transition and the liquid-vapor transition are found. The influence of exchange interactions and an external magnetic field on the structure of the liquid magnet is studied.
