Abstract: Hard magnetic [L1.sub.0]-[Fe.sub.51][Pt.sub.49] thin films with out-of-plane texture and film thicknesses are prepared on MgO(001) single crystalline substrates by co-sputtering and are magnetically examined by SQUID magnetometry at different temperature range. The microstructural parameters are ascertained by studying the temperature dependence of the coercivty within the framework of micromagnetism, which has helped in understanding the magnetic reversal process.
