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