Abstract

Heat capacity and ac-susceptibility measurements under high pressure are carried out in SmOs4Sb12. Application of pressure increases the Curie temperature TC and enhances the heat-capacity jump at TC. On the other hand, the peak value of ac-susceptibility at TC decreases above 1 GPa and then almost vanishes at 3.6 GPa. These experimental facts suggest that the ordered state in SmOs4Sb 12 is not simple ferromagnetic state but possibly multipolar ordered state.
