Abstract

The investigation of magnetic properties of self-doped LaMn _1-xO₃ manganites (0≤x≤0.06) under hydrostatic pressure up to 12 kbar was discussed. The ferromagnetic moment at T=5K increases significantly while the pressure coefficient of T_N decreases significantly, with increasing self-doping. It was observed that for x=0.06, transition temperature becomes pressure independent while magnetization markedly decreases with increasing pressure. It was shown that suppression of the ferromagnetism under pressure was tentatively attributed to the development of antiferromagnetic domains capable of competing with the ferromagnetic order under pressure.
