Abstract
In this work Sr doped BiFeO3 (BSFO) and CoFe2O4 (CFO), (BSFO-CFO) composite polycrystalline samples are prepared via simple solid state route. We report the existence of an irreversible room temperature field-induced a ferromagnetic (FM) transition that does not quench even after removing the magnetic field in BSFO and CFO composite system. The field induced FM order transition occurs over a long range of temperature from 330â¯K to 5â¯K and remain stable for at least 45â¯min after the field quenching. The fraction of field induced FM phase increases and its decay rate decreases at lower temperatures. The strong temperature dependence of the magnetic field induced FM phase is also observed. These findings will lead the researcher to design new composite materials system for desired applications.
