High pressure synthesis of BiCrO3, a candidate for multiferroism

Résumé

The synthesis and the thermal stability of the high pressure and high temperature perovskite phase BiCrO3 have been studied. BiCrO3 can be synthesized in a wide range of pressure (1-6GPa) and temperature (690-865C). The thermal behavior of BiCrO3 depends on the atmosphere : it tends to be stable under inert gas whereas it decomposes at 650C under O2. The melting point of BiCrO3 is determined by DTA under argon and a value of 1040C is proposed. First SEM and TEM observations are also presented.
