    • We have measured the parallel and perpendicular (relative to the molecular plane) microwave resistivities at ambient pressure as a function of temprature with a contactless microwave cavity perturbation technique at 17 GHz. Below 50 K, the Mott-insulating state is signaled by a rapid increase of the resistivity; we observed, however, a change in the rate of increase (dip in dρ/dT) around 34 ± 2 K just above the AF transition [10], which is signaled at 27 K on the resistivity by a strictly linear temperature dependence of ρ(T). This dip in dρ/dT in the insulating phase has its counterpart in the metallic phase where a peak in dρ/dT, associated with the crossover line, is rather observed. This dip in dρ/dT at T = 34 K and P = 1 bar is indicated as a dotted hexagon on the phase diagram of Fig. 1.
