摘要：
We have studied the magnetic properties of Dy2Co17 - xSix compounds (x less than or equal to 3) by means of magnetic measurements and X-ray diffraction on magnetically aligned powders. The Curie temperature and the spontaneous moment decrease strongly with increasing Si concentration. All compounds show easy-plane anisotropy in the whole temperature range investigated. From high-field-magnetisation measurements at 5 K and from magnetisation measurements at the compensation temperature, the intersublattice exchange coupling was determined and found to be hardly dependent on the silicon content.
