Lambda type anomaly

Studies on the thermal properties of lanthanum, cerium, neodymium, and gadolinium hexaborides in the cryogenic region from 5° to 350°K. 193) have shown the presence of two types of anomalies in the latter three substances. At temperatures near 10 °K. there appears a lambda-type anomaly in each which is rather characteristic of a magnetic transformation. At slightly higher temperatures this is followed by Schottky-... 

Also other studies of type-1 EugGaigGe3o have provided evidence for a second feature at a characteristic temperature below Tc- For instance, the magnetic specific heat, in addition to the lambda-type anomaly at Tc, shows a broad shoulder at about 10 K [10]. This anomaly is more clearly revealed by the temperature dependence of the magnetic entropy change [47] that will be further discussed in the context of magnetic refrigeration in the next section.
