Multiple magnetic transitions in multiferroic BiMnO$_{3}$ under high pressure

POSTER

Abstract

Multiple magnetic transitions, named as kinks I, II and III, under hydrostatic pressure on multiferroic BiMnO$_{3}$ have been studied by the dc magnetization, magnetic hysteresis, and ac susceptibility. The proposed phase diagrams at ambient pressure, 9.4 and 11.9 kbar show the different magnetic features with various magnetic fields. These findings are believed to result from the variations of crystal structure influenced by the external pressure. These results also indicate the common complicated correlation between the lattice distortion and the spin configuration in multiferroic system.
