A theoretical study of the magnetic properties of the intermetallic compound ThCo(5) was performed by means of the fixed-spin-moment method. Metamagnetism was found in accordance with experimental observations, although only for slightly smaller volumes than the experimental equilibrium volume. It was found that there were two distinctly different local cobalt magnetic moments for the lower magnetic state, whereas for the higher magnetic state, the two cobalt moments were nearly the same size. These findings are discussed in terms of the calculated electronic structure. Appreciable orbital magnetic moments on the cobalt atoms are obtained when spin-orbit coupling is included in the calculations. The volume dependence of the theoretically calculated magnetic properties and its influence on the metamagnetic transition are discussed.
