摘要

Mössbauer spectra of MnCo0.65Fe0.35P recorded between 100 K and 573 K prove that the competition between ferro- and antiferro - magnetic couplings of Fe is determined by its two nearest (Co, Fe) metallic neighbours. Novel interpretation of the corresponding temperature dependence of the bulk magnetic properties is given. The macroscopic magnetic properties directly result of the statistical distribution of Co and Fe ions in identical crystallographic positions. In MnFeP0.5Si0.5 Fe is located in a tetrahedral site formed by non-metallic (Si, P) atoms, with five possible configurations. The Mössbauer spectra recorded between 84 K and 310 K show that the distribution of P and Si induces small additional contributions on the magnetic hyperfine fields on the Fe sites.
