MAGNETIC COMPENSATION EFFECT IN TBFE1-XALXO3 SYSTEM

Magnetic susceptibility measurements for solid solutions of TbFe1-xAlx O3, in the whole range of Al concentration, have been carried out. The obtained results indicate an essential role of the Al substitute in t he magnetic behaviour of examined compounds. The generation of compens ation effect, which modifies the susceptibility of the system, seems t o be of particular interest. The compensation temperatures have been d etermined from some singularities visible on susceptibility curves for compounds with Al concentration 0.06 less than or equal to x less tha n or equal to 0.70.
