Magnetocrystalline anistropy of Y3Fe27.4Ti1.6

Abstract A spinning-sample-magnetic-alignment method has been used to align fine-powdered ( μ m) Y 3 Fe 27.4 Ti 1.6 . A nearly perfect magnetic alignment was confirmed by X-ray diffraction on magnetically-aligned sample. The easy magnetization direction of Y 3 Fe 27.4 Ti 1.6 is determined to be within the (204) plane and has angle of 60° to the c -axis. The anistropy field H A of Y 3 Fe 27.4 Ti 1.6 was determined, from 4.2 K to the Curie temperature, directly on the magnetically-aligned sample by using the SPD technique in a pulsed-field magnetometer. The Curie temperature of the Y 3 Fe 27.4 Ti 1.6 was determined by measuring the temperature dependence of the ac susceptibility from 300 to 800 K. The presence of a small amount of a Y(Fe,Ti) 12 phase in the Y 3 Fe 27.4 Ti 1.6 sample is traced by susceptibility measurements.
