We present measurements of the temperature dependence of the electrical resistivity ρ(T) of CeRhSn up to ∼27 kbar. At low temperatures, ρ(T) varies linearly with T for all pressures, indicating non-Fermi liquid behavior. Below T(f) ∼ 6 K, ρ(T) deviates from a linear dependence. We found that the low-T feature centered at T = T(f) shows ...

An accurate in situ electrical resistivity measurement of cuprous oxide cubes has been conducted in a diamond anvil cell at room temperature with pressures up to 25 GPa. The abnormal electrical resistivity variation found at 0.7-2.2 GPa is attributed to the phase transformation from a cubic to a tetragonal structure. ...
