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 μB / 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.
