Abstract
In this lecture we would like to demonstrate that the magnetisation and magnetostriction studies in the vicinity of orientation phase transitions in antiferromagnets, induced by a magnetic field (the so-called spin-flop transition), supplemented by the data on the pressure dependences of the transition field Hc, Neel temperature TN and Curie temperature Θ, may elucidate the nature of magnetic anisotropy in the antiferromagnet under study as well as of the exchange energy dependence on the interatomic distances. These dependences are quite complicated. In order to describe them both configurations of magnetic sublattices and the positions of non-magnetic ions should be taken into account The both are involved into indirect exchange interaction.
