The electrical resistivity of single crystalline HoNi 2 B 2 C has been measured at high pressure and magnetic fields. The three anomalies in the magnetoresistance due to metamagnetic transitions are observed both at ambient and high pressures. It is found that the metamagnetic transition fields increase with increasing pressure. The temperature dependence of electrical resistivity is strongly dependent on magnetic field. Non Fermi liquid behavior is observed near the metamagnetic transition fields. But the normal Fermi liquid behavior recovers after completing the phase transition. The Grüneisen parameters are also calculated to examine the stability of electronic state.

We report the effect of Cr doping on the structural, magnetic, and electrical transport properties in Cr-doped antiperovskite compoundsGaCFe3−xCrx(0≤x≤0.9). With increasing the Cr contentx, the lattice constant increases while both the Curie temperature and the saturated magnetization decrease gradually. The electrical resistivity shows different behaviors as a function ofx. Forx≤0.6, there exists a semiconductor-like behavior below a certain temperature which decreases with increasingx. In contrast, for0.7≤x≤0.9, the resistivity shows a metallic behavior in the whole temperature measured (2–350 K). In particular, the Fermi-liquid behavior is obtained below 70 K. Finally, based on the magnetic and electrical properties ofGaCFe3−xCrx(0≤x≤0.9) a magnetic/electrical phase diagram was plotted.
