77K and in an applied magnetic filed.The experimental results reveal that （1） the P（H hf ） curves of Fe 90-x Cr xZr 10 （x=30

which means that they are strong ferromagnets

and the low-filed spin（moment） fractions vary with Co（Cr） content

temperature

applied magnetic filed and hydrogenation;and anomalous behavior exists in Co-poor Fe-（Co

Cr）-Zr alloys

indicating the magnetic inhomogeneity and Invar character;（2） the degree of disorder of spins for Fe-（Co
