Abstract

In this communication, we compare effects of hydrostatic and chemical pressure on the magnetic properties of La0.67Ca0.33(CoxMn1−x)O3 ceramics. For ceramics with x = 0.03, the Curie temperature TC increases under hydrostatic pressure with a slope dTc/dp = +23.4 K/GPa. The saturated magnetization μs does not change with applied hydrostatic pressure. Chemical pressure was induced by substitution of Co for Mn. The substitution from x = 0.03 to x = 0.1 reduces the volume of the elementary cell by about 0.28 %, but TC decreases from 203.4 to 167 K. The saturated magnetization μs is not affected by this substitution.
