The magnetizations of single crystals with x = 4, 6, 8 and 10% by weight have been measured at 4.2 K using a vibrating-sample magnetometer and a superconducting quantum interference device (SQUID). The magnetizations of the alloy at these low concentrations and at 0 K have been theoretically determined by using the tight-binding linearized muffin-tin orbital method coupled with augmented-space recursion. The theoretical data are compared with the experiment.
