摘要：

A spinning-sample-magnetic-alignment method has been used to align fine-powdered ( < 20 mu m) Y3Fe27.4Ti1.6. A nearly perfect magnetic alignment was confirmed by X-ray diffraction on magnetically-aligned sample. The easy magnetization direction of Y3Fe27.4Ti1.6 is determined to be within the (204) plane and has an angle of 60 degrees to the c-axis. The anisotropy field H-A of Y3Fe27.4Ti1.6 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 Y3Fe27.4Ti1.6 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 Y3Fe27.4Ti1.6 sample is traced by susceptibility measurements.
