Abstract
Normal and superconducting states of BaNi2P2 single crystals (TC∼2.4 K) have been studied. Anisotropy of resistivity is comparable with that of upper critical fields, indicating the effective mass estimated in the normal state is nearly the same as that in the superconducting state. From magnetization hysteresis with a weak vortex pinning, lower critical fields are estimated. Hall effect is explained by a two-carrier model consistent with a multiple-band with both hole and electron characters. It has been proved that BaNi2P2 is an anisotropic three-dimensional intermetallic superconductor.
