摘要

We present the anisotropic electrical and thermal transport coefficients (electrical resistivity, magnetoresistance, thermoelectric power, thermal conductivity), the magnetic properties, the specific heat and the electronic density of states of a monocrystalline In_3Ni_2 intermetallic compound, representing a precious-metal-free (and noblemetal- free) intermetallic catalyst for the selective hydrogenation of α,β-unsaturated aldehydes. The investigated physical parameters were determined along three orthogonal crystal-symmetry directions of the trigonal structure, the twofold axis, the 3-bar axis and within the mirror plane. All the investigated tensorial and vectorial quantities show the same anisotropy, with the quantities being isotropic for the twofold direction and in the mirror plane, whereas there is small, though still significant anisotropy to the 3-bar direction. The In_3Ni_2 crystal conducts the electricity and heat somewhat less efficiently along the 3-bar direction than along the twofold direction and in the mirror plane, but the differences are not large, of about 20%. In_3Ni_2 is a diamagnetic intermetallic compound, with a presumably simple Fermi surface and electrons as the majority charge carriers.
