英文摘要
We have demonstrated the effect of pressure on the magnetization step and its associated magnetostriction in the bilayered and cubic manganites. These findings strongly suggest a crucial role of the frozen phase separated state in the field induced step like transition. A colossal electro resistance effect in the bilayered manganite is also observed at lower temperatures. Furthermore, anomalously negative magnetization of Sb substituted electron doped manganites is reported.
