Research Abstract |
In this study, the transport properties of single crystals of CePtSi2 and its relative materials under pressure and in magnetic fields were measured to reveal the origin of the pressure-induced superconductivity, large magnetoresitance, and anisotropic Kondo scattering in CePtSi2. The main results are shown below. (1) The transport properties under pressure for each crystal axis indicated that the pressure-induced superconductivity in CePtSi2 is mediated by the influence of valence fluctuation.(2) The magnetoresistance effect is large for c-axis, but very small for b-axis. This suggests that the anisotropic magnetoresistance and Kondo scattering have the same origin.
