Preferential Silicon Site Occupation in Y2Fe14-xSixB
Neutron-diffraction and Mössbauer effect studies of Y2Fe14-xSixB, where x is 0.28, 0.67, and 1.87, show that silicon preferentially occupies the 4c site in the R2Fe14B structure. If the breaking of short iron-iron bonds is the mechanism for the increase in the Curie temperature of R2Fe14-xSixB, then the bonds most responsible for the increase are those between iron atoms on the 16k2 and 4c sites.
