| Abstract: | The spin-polarized method is employed to calculate the electronic structure of the serial model compounds Y2Fe17Cx (x= 0. 1. 2. 3). The magnetic properties of those comPOunds are discussed bysystematic comparision. It is proved thst volume expansion is the main factor in increasing the magnetic moments in those intermetallic compounds. |
