TL;DR: Itinerant electron metamagnetism has been found in C15-type Laves phase compound Lu(Co 0.94 Al 0.06 ) 2. The transition field was 220kOe at 4.2 K and the maximum moment per Co atom reached the value 0.75 μ B at 400 kOe as mentioned in this paper.
Abstract: Itinerant electron metamagnetism has been found in C15-type Laves phase compound Lu(Co 0.94 Al 0.06 ) 2 . The transition field was 220 kOe at 4.2 K and the maximum moment per Co atom reached the value 0.75 μ B at 400 kOe. The temperature dependence of susceptibility of this sample was obtained from the Knight shift data of 59 Co. Exchange enhancement in the susceptibility was more remarkable than for the sample with lower Al concentration. These results are consistent with the theory of itinerant electron ferromagnetism showing the importance of the shape of the density of state curve near the Fermi level.

TL;DR: In this paper, the properties of the alkaline earth filled skutterudite AFe4Sb12 (A = Ca, Sr, Ba ) were investigated by high-field magnetization measurements in a pulsed magnetic field.
Abstract: Magnetic properties of the alkaline earth filled skutterudite AFe4Sb12 ( A = Ca , Sr , Ba ) , which are located in a proximity to a ferromagnetic instability, have been investigated by the high-field magnetization measurements in a pulsed magnetic field. At 1.3 K, in CaFe4Sb12, a metamagnetic increase of magnetization appears at 13 T where M reaches about 0.25 μ B / Fe . This metamagnetic anomaly weakens and the critical field shifts to a lower field in sequence of A = Ca , Sr , Ba . The temperature variation of the metamagnetism has also been investigated, and the results are discussed in relation to the ferromagnetic instability.
