The structure and magnetic properties of mechanical alloyed Fe80(Y2O3)20

Changes in structure and magnetization of Fe 80 (Y 2 O 3 ) 20 made by the mechanical alloying have been examined by the extended X-ray absorption fine structure (EXAFS) study and the vibrating sample magnetometer (VSM). EXAFS study and temperature dependence of magnetization show that the metastable alloy is the mixture of iron itself and iron-oxide compounds.
