The behavior of different magnetic properties (saturation magnetization and magnetostriction) of Fe73.5Cu1Nb3Si13.5B9 nanocrystalline alloy exhibiting a biphase character has been assumed to be the algebraic sum of the contributions arising from the partial volume of both phases is investigated. Experimental results of the mentioned properties obtained in the classical mentioned nanocrystalline alloys seem to indicate the validity of the two volumetric contributions, although some discrepancies could suggest the relevance of another contribution coming from the surface region of the nanograins.

    The phase stability and magnetic properties of the half-metal-type Co2Cr1-xFexAl alloy system were investigated. It was found that the occurrence of two-phase separation is unavoidable in a concentration range of less than x=0.4, leading to deviation of the saturation magnetic moments from the...
