The magnetic properties of the ferrimagnetic cobaltite CaBaCo4O7 are systematically investigated. We find that the susceptibility exhibits a downward deviation below ∼ 360 K, suggesting the occurrence of short range magnetic correlations at temperature well above TC. The effective moment is determined to be 4.5 μB/f.u, which is consistent with that expected for the Co2+/Co3+ high spin species. Using a criterion given by Banerjee [Phys. Lett. 12, 16 (1964)], we demonstrate that the paramagnetic to ferrimagnetic transition in CaBaCo4O7 has a first order character.
