Investigation of phase formation of RFe11V1 − xTix (R = Pr, Ce) compounds

摘要: Phase formation of PrFe11V1 − xTix and CeFe11V1 compounds with the ThMn12-type structure has been investigated by x-ray diffraction (XRD), differential thermal analysis (DTA) ac initial susceptibility. The stable temperature range 1-12 phase for alloys constructed as a function Ti content. It is found that PrFe11V compound do not form. PrFe11Ti can only be obtained annealing at narrow between 1030 °C 1113 °C. Furthermore, lower wider decreasing content x(0.2 ≤ x 1). CeFe11V CeFe11Ti synthesized, it more favorable to synthesis single pseudotenary compounds. For = 0.2–1, lattice parameters c vary very much: around 0.860 0.479 nm, Curie Tc 268 °C–329 are 0.857 0.478 211 °C–252
