OSTI ID:177457
The microstructure, crystallography and magnetic properties of the RT1Fe11XCoX alloys were examined. It was found that Fe and Co are completely miscible in this system and crystallize in the ThMn12 structure. The initial replacement of Fe by Co in the Curie temperature significantly and then more slowly with further Co substitution. The magnetic moment exhibits a maximum value at x approx 4. The magnetic anisotropy of the rare earth sublattice appears to be planar for the rare earth with positive second order Stevens factor (i.e. Er) and axial for the rare earths with negative second order Stevens factor (i.e. Tb, Dy and Ho) in the RTiCo11 alloy system. This behavior is the opposite of that observed in RTiFe11. The magnetic anisotropy phase diagrams of the RTiFe11-xCox systems were determined. RTiFe11-xCox Alloys, Magnetism, ThMn12 Structure.
