Magnetic Properties of Nanocrystalline Pyrrhotite Prepared by High-energy Milling

Czechoslovak Journal of Physics Aims and scope

Abstract

The nanocrystalline pyrrhotite was prepared by high-energy milling of lead sulphide with elemental Fe acting as reducing element. X-ray diffractometry, Mössbauer spectroscopy and VSM magnetometry were used for to determine the properties of nanocrystalline iron sulphide prepared by the corresponding mechanochemical reaction. Pyrrhotite Fe1-xS together with the residual Fe metal were identified by the X-ray diffractometry. The kinetic studies performed by Mössbauer spectroscopy and VSM magnetometry allowed us to follow in more details the progress of the nanocrystalline magnetic phase formation during the milling.
