| Abstract: | In the pseudobinary intermetallic compounds Zr(Fe1-xCox)2 (0?x?0.2) the hyperfine fields of all nuclei present are investigated by means of Mössbauer effect and NMR. While for the “nonmagnetic” site the Zr-hyperfine field depends on the configuration of the nearest Fe, Co neighbours, no such effect is observed for the hyperfine fields on the “magnetic” sites. A large pseudodipolar interaction is observed for the Fe and Co atoms, from which the coexistence of several directions of magnetization can be deduced. The easy direction seems to be determined by the respective Fe/Co configuration. |
