Abstract
Composites consisting of mixture of a Fe-Co alloy and a mixed Fe-Co fe rrite have been studied together with the pure spinel phase extracted from the composite. They are prepared by a new chemical route. Detaile d Mossbauer studies allow the determination of the chemical formulas i ncluding the Fe and Co populations in the two spinel sites. Mossbauer study under applied field reveals the presence of a randomly canted sp in structure in the spinel. The results are in agreement with the magn etization measurements.
