Abstract

We have succeeded in synthesizing PrFe11V1-xTix (x=0.2-1) compound and their nitrides with the ThMn12-type structure. The phase formation and magnetic properties have been investigated by x-ray diffraction, differential thermometric analysis, and magnetic measurement. The stabletemperature range of the 1-12 phase for PrFe11V1-xTix alloys has beendetermined as a function of Ti content. PrFe11V compounds with the ThMn12-type structure do not exist and PrFe11Ti compounds with the TnMn(12)-type structure are obtained by annealing in a narrow temperature range between 1303 and 1383 K. Furthermore, 1-12 phase with the ThMn12-type structure can be obtained at lower temperature and wider temperature range with decreasing Ti content x (0.2 less than or equal to x less than or equal to 1). PrFe11V1-xTixNy with x=0.2-1 has a T-c of about 730-785 K, B-a larger than 8 T and M-s in the range 144-148 emu/g. These intrinsic magnetic properties are highly favorable for permanent magnet applications. As a preliminary, an intrinsic coercivity of 5.4 kOe is obtained for PrFe11V0.5Ti0.5Ny at room temperature by using mechanical alloying technique. (C) 1997 American Institute of Physics.
