MAGNETIC PROPERTIES OF SOME INTRA-RARE EARTH ALLOYS
Paramagnetic susceptibilities of samarium structure alloys in the systems La--Gd, Nd--Y, Nd--Tm, and Ce--Y were measured from 4.2 to 300 deg K to determine what effect the formation of this structure had on the magnetic properties of the alloys. Susceptibility maxima were observed in the Nd--Y and Nd--Tm alloys, at 34.5 and 28.5 deg K, respectively. Slope charges were observed in the curve of 1/X versus T for the La--Gd alloy at 155 and 130 deg K, and the susceptibility of this alloy remained temperatureindependent from 130 to 7 deg K. A rather poorly defined region of constant susceptibility was also observed for the Ce--Y alloy, from 26 to 37 deg K. Above these transition temperatures, the alloys obeyed the Curie-Weiss law, the susceptibilities of the La--Gd and Ce--Y samples indicating the possibility of electron transfer occurring in these cases.
