A far-from-equilibrium preparation route and using a particular combination of starting materials led us to obtain nonstoichiometric Y(Fe,V)12and its interstitial carbide. Structural analysis and EDAX results reveal the formation of the main 1:12 phase with the ThMn12-type structure, with 13–15% vacancies at the 3dmetal sites. Insertion of interstitial carbon increases the TCand magnetization of the 1:12 phase, whereas the unit cell volume remains unchanged. The effects of vacancies and interstitial carbon on the Mössbauer hyperfine fields and isomer shifts are discussed with reference to the calculated quantities. |
