Metamagnetic transition of ScCo2and LuCo2

The electronic structure of d electrons in the cubic Laves phase of the intermetallic compounds ScCo 2 and LuCo 2 under an external magnetic field is calculated in the tight-binding approximation and in the Hartree-Fock approximation. The field dependence of the induced moment is obtained at 0K. It is shown that the metamagnetic transition from the paramagnetic to the ferromagnetic state can occur at about 120 and 94 T for ScCo 2 and LuCo 2 , respectively.
