Anomalous low-temperature resistivity exponent of CeIn3 at the border of magnetic and superconducting order

The low-temperature resistivity of CeIn 3 has been measured at temperatures above the superconducting transition in the vicinity of the critical pressure (27.5 kbar) where the Neel temperature is suppressed to zero. With these measurements, it has been demonstrated that the resistivity exponent in CeIn 3 locks into a value of the order of 1.5 at low temperatures.
