摘要：
Anisotropic superconducting properties of intermetallic compounds MgB2, Y2PdGe3, and CaAlSi with AlB2 structure are studied by detailed angular dependent transport measurements. MgB2 and CaAlSi shows appreciable anisotropy of the upper critical field, H-c2, with mass anisotropy parameter gamma = 3 and 2, respectively, while Y2PdGe3 is almost isotropic. In-plane anisotropy of H-c2 in these hexagonal superconductors is very small, consistent with the prediction based on GL theory.
