摘要: We have considered magnetic and magnetoelastic characteristics of a van Vleck paramagnet LiTmF4 taking into account the interaction between thulium ions via phonon field. calculated parameters multipole that is caused by Tm3+ with dynamic lattice deformations Bg symmetry. presented self-consistent description previously published results measurements temperature dependences elastic constants nonlinear Zeeman effect in optical spectrum single crystal, as well magnetostriction on temperature, magnitude, direction external
