Streszczenie

We report on a detailed investigation of magnetic susceptibility χ (T, B), magnetization M(T, B) and specific heat Cp(T, B) for a polycrystalline sample of Co(C3H4N2)2(CO3)(H2O)2. Ground state for Co2+ has found to show an unquenched spin–orbit coupling and a weak antiferromagnetic interaction between Co ions. Application of magnetic field significantly affects the magnetization and specific heat at T < 20 K. Anomaly observed in Cp(T, H)-dependences may be interpreted in terms of the conventional two-level (doublet–singlet) Schottky model. Both energy gap between these levels and the coefficient of the electronic specific heat are strongly field dependent.
