Abstract
The structure of the ground state of a narrow-band Hubbard magnet is i nvestigated in the t-J model. The low-temperature thermodynamics of th e ferromagnetic state is studied. The behaviour of the susceptibility of SmBa2Cu3O6.3 such as a paramagnetic increase in 1/T law and a maxim um at T approximate to 0.3 K, is explained in the model of a narrow ba nd with metallic conductivity.
