SATURATION MOMENT, SPECIFIC-HEAT, AND TRANSPORT-PROPERTIES OF DISORDERED CO100-XPTX ALLOYS

A series of Co100-xPtx alloys were made in an induction furnace. To ma ke the the alloys in a disordered state, they were heated up to 950-de grees-C, and then quenched in salt water. Experimental quantities meas ured include saturation moment, specific heat, residual resistivity, a nd anisotropic magnetoresistance at low temperatures. By comparing tho se data with those for the Fe100-xCrx, Fe100-xMox, Fe100-xWx, Co100-xN ix, and Co100-xPdx alloys, we are able to have a complete discussion f rom the framework of the split-band model. For Co-Pt alloys, the elect ronic-specific-heat coefficient has no minimum, and the anisotropic ma gnetoresistance shows no global maximum either.
