Structure, Magnetic Properties and Magnetostriction of PrxTb1-x (Fe0.6Co0.4)1.9 Alloys
The structure, magnetic properties and magnetostriction of Pr<,x>Tb<,1-x> (Fe<,0.6>Co<,0.4>) <,1.9> alloys were investigated. It was found that Pr <,x>Tb<,1-x> (Fe<,0.6>Co<,0.4>)<,1.9> alloys with x <0.4 were composed of single cubic Laves phase, while a mass of PuNi<,3>-type phase appeared when the Pr concentration was higher than 0.4. The magnetization measurement showed that there were two different magnetic phases in Pr<,0.2>Tb<,0.8>(Fe<,0.6>Co<,0.4>) <,1.9> alloys. The saturation magnetostriction of Pr <,0.2>Tb<,0.8> (Fe<,0.6>Co<,0.4>)<,1.9> alloys at 900kA·m<,-1> is 1765x10<,-6>, which was higher than that of Tb <,0.27>Dy<,0.73>Fe<,2> (1600x10<,-6>). The spontaneous magnetostriction λ<,111> showed a maximum value at x=0.3.
