For ceramics with x=0.03, the Curie temperature TC increases under hydrostatic pressure with a slope d TC /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. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2011
