The Effect of Ce doping on the Magnetic Properties of NdFe11Ti alloys

Abstract

The studied alloys exhibit good magnetic properties that attracts the interest of future research, which could lead to its commercial and industrial applications. The investigation of the structure and magnetic properties of (Nd1-xCex) Fe11Ti alloys, revealed that, Ce doping has effect on the structure and magnetic properties of the alloys after arc-melting process. The main phase of the processed alloys are compounds with ThMn12-type structures (I4/mmm). After smelting (as cast), the main phases resulted to have volume fractions of 74 - 80 vol.% and an average grain size of 100 - 150 nm. The volume of the unit cell is nearly the same by a unit difference with impurities as the remaining phase. Where the values that does not exceed 10 - 15 vol.% of the alloys composition. The phase structure inhomogeneity (crystalline multiphase state and dendritic segregation) of the alloys in the cast state explained as the result of change in hysteresis properties.
