Abstract
Fine particles of α-Fe are prepared by the reduction in H 2 of lepidocrocite in the presence of MoS2, which allows the reduction to take place with restricted coalescence of the starting particles. Magnetic moments and coercivities are determined at the temperature during processing. Results are given for magnetization measurements, electron microscopy, Mossbauer effect spectroscopy, and X-ray diffraction. Enhanced coercivities are observed when MoS2 is present. Surface pinning, deduced from the approach to magnetic saturation, is likely at the interface between the metallic particle and a surface oxide layer
