Abstract

Magnetic phases of an amorphous Ge₆₃Fe₃₇ amorphous thin film, fabricated by thermal co-evaporation onto oxidized Si at room temperature, are investigated. Various magnetic measurements show ferromagnetic ordering even at room temperature and a spin glass phase below 20 K. A scaling analysis of the spin glass phase indicates the existence of long-range exchange interactions, providing evidence of a large number of carriers in an amorphous diluted magnetic semiconductor.
