On the Landau-Ginzburg theory the metamagnetic transition observed at low temperature in some Co-compounds YCo2, LuCo2, Co(S, Se)2 and others has been shown to be related with the susceptibility maximum at room temperature through a characteristic quantity given in terms of the Landau expansion coefficients of the magnetic free energy. The present theory can explain the metamagnetic behaviours observed in the d-electron system at finite temperature.
