Abstract
All the magnetic properties of TmZn have been explained in a recent past for the cubic paramagnetic phase in particular through a susceptibility formalism taking into account the crystalline electric field, the bilinear exchange, the magnetoelastic coupling and the quadrupolar pair interactions. However, the corresponding set of parameters fails for describing the ferromagnetic tetragonal phase properties, in particular the magnetization processes. We first present here polarized neutron diffraction results which prove that the conduction band magnetization is quite negligible in this compound. Within the same basic Hamiltonian, new parameters must then be determined, relevant for the ordered phase. A new set is obtained describing magnetization and magnetostriction processes and the magnetic excitations. The important changes of the crystalline electric field and of the bilinear exchange are discussed in relation with the large tetragonal strain induced by the quadrupolar ordering.
