摘 要:Magnetic and structural properties of YCo_(12-x)Ti_(x) compounds have been investigated by x-ray diffraction an magnetic measurements.X-ray diffraction patterns of aligned powder samples indicate that the easy magnetiB zation direction at room temperature is along the c-axis for all the *** lattice parameters increase monotonously while Curie temperature TC decreases with increasing Ti *** was found that all the com pounds investigated are strong ferromagnets by analysis of magnetic moments using a magnetic valence *** values of anisotropy fields B_(a)at room temperature and 1.5K decrease with increasing *** easy-axisanisotropy of the YCo_(12-x)Ti_(x)compounds is mainly contributed by the Co atoms at 8i sites according to the individual-site-anisotropy model.
