Abstract： Magnetic and structural properties of YCo12-xTixcompounds have been investigated by x-ray diffraction and magnetic measurements. X-ray diffraction patterns of aligned powder samples indicate that the easy magnetization direction at room temperature is along the c-axis for all the compounds. The lattice parameters increase monotonously while Curie temperature TC decreases with increasing Ti content. It was found that all the compounds investigated are strong ferromagnets by analysis of magnetic moments using a magnetic valence model. The values of anisotropy fields Ba at room temperature and 1.5K decrease with increasing x. The easy-axis anisotropy of the YCo12-xTixcompounds is mainly contributed by the Co atoms at 8i sites according to the individual-site-anisotropy model.
