Abstract
- Exchange coupled NiFe<subscript>2</subscript>O<subscript>4</subscript>-CoO nanocomposite (NFOC) was synthesized by polyol process using NiFe<subscript>2</subscript>O<subscript>4</subscript> seed. The nanocomposite was characterized by x-ray diffraction (XRD), transmission electron microscopy (TEM) and SQUID magnetometer. A Field cooled hysteresis curve of NFOC at 4 K is clear signature of strong internal interaction and co-existence of different magnetic phases into the individual particles. The strong interfacial exchange coupling between the AFM and FiM part results in high value of coercivity with completely shifted loop along negative field axis. [ABSTRACT FROM AUTHOR]
