Abstract

We grew single crystals of a ferromagnet LaCo₂P₂ and an antiferromagnet CaCo₂P₂, and clarified the magnetic properties by measuring the electrical resistivity, specific heat, magnetic susceptibility, and magnetization. For LaCo₂P₂, we also carried out the de Haas-van Alphen (dHvA) experiment. Detected dHvA branches are well explained by the results of energy band calculations using a full-potential linearized augmented plane wave method within the local spin density approximation, where the ferromagnetic state is assumed. The cyclotron effective masses are (2-3)m₀ (m₀: rest mass of an electron). The present relatively large cyclotron masses in LaCo₂P₂ are due to ferromagnetic correlations of Co-3d conduction electrons, which are compared with much larger cyclotron masses of (3-7)m₀ for a nearly ferromagnet SrCo₂P₂.
