Application of the underscreened Kondo lattice model to neptunium
... Thus, our model can give a good explanation of the magnetization curves of the NpNiSi2 compound, if we take the Kondo temperature TK equal to T ∗ of order 12 K, which is clearly much smaller than the Curie temperature TC =51.5 K. There is another ferromagnetic and Kondo neptunium compound, namely Np ...
