Pr1-xLaxCo5-y (x=0, 0.15. 0.25, 0.35,1.0, y=0.5, 0.7, 0.9, 1.0) alloys were investigated. The effect of the variation of x and y on magnetic properties and thermal stability of the alloys were studied. The magnetic properties for the Pr0.85La0.15Co4.3 and Pr0.75La0.25Co4.1 magnets are iHc=368 kA/m, Br=0.91 T, (BH)max=145.6 kJ/m3, αBr=-0.03%/℃ and iHc=568 kA/m,Br=0.8 T, (BH)max=127.2 kJ/m3,αBr,=-0.06%/℃, respectively The phase structures of as-cast alloys and magnets were investigated
The effect of the variation of x and y on magnetic properties and thermal stability of the alloys, Pr1-xLaxCo5-y (x = 0, 0.15. 0.25, 0.35, 1.0, y = 0.5, 0.7, 0.9, 1.0) were studied. The magnetic properties for the Pr0.85La0.15Co4.3 and Pr0.75La0.25Co4.1 magnets were iHc = 368 kA / m, Br = 0.91 T, (BH) max = 145.6 kJ / m3, 0.03% / ° C and iHc = 568 kA / m, Br = 0.8 T, (BH) max = 127.2 kJ / m3, αBr, = - 0.06% / ° C, respectively The phase structures of as-cast alloys and magnets were investigated
