@@Half metallic materials have recently attracted much attention due to their high spin polarization, important for research and application in spintronics . As a promising candidate, ultrathin films of magnetite Fe3O4 have motivated numerous investigations on their structure and magnetic properties. In this paper, we report the investigations on growth and magnetic properties of ultrathin monocrystalline Fe3O4 films on GaAs(100) and InAs(100).

The magnetic materials with large magnetocaloric effect have attracted considerable attention for magnetic refrigeration applications. Recently, Gd based soft magnetic amorphous alloys have been proposed as promising candidates for magnetic refrigeration. Owing to the amorphous nature, they exhibit some special advantages such as the negligible magnetic hysteresis losses and tunable Curie temperature Tc. Zhang et al.(1' found that two successive magnetic-entropy changes occur in the compounds Gd4Co3 due to a spin-reorientation transition at Tsr=163 K and a ferrimagnetic-magnetic ordering transition at 7c=220K. In this work, the magnetic properties and magnetocaloric effect of amorphous (Gd4Co3)95 alloy are investigated. The nature of the ferrimagnetic to paramagnetic phase transition was performed a critical exponent study.
