The temperature dependence of the saturation magnetization and the first and second anisotropy constants have been determined for alloys in the system Pr/sub x/Sm/sub 1-x/Co/sub 5/. The alloys studied were spheres cut from single crystals grown by the Bridgeman drop technique. Measurements were made on a Foner vibrating sample magnetometer. The anisotropy constants were calculated statistically from hard direction magnetization data by the method of Sucksmith and Thompson. M/sub s/, K/sub 1/, and K/sub 2/ for PrCo/sub 5/ were found to be larger than previously reported values at low temperatures. PrCo/sub 5/ and Pr/sub 0.75/Sm/sub 0.25/ are both magnetically easy come at low temperatures. K/sub 2/ increases with increasing Sm content in the Pr-rich alloys. However, K/sub 2/ values for the Sm-rich alloys are anomalously large.
