Fig. 2: In-plane resistivity of AgCrSe2 as a function of temperature under perpendicular magnetic fields.
a ab plane resistivity as a function of temperature with different applied out of plane magnetic fields μ0H = 0…14 T. With a large enough field of μ0H ≳ 14 T metallic behaviour can be observed in the entire temperature range 2 K ≤ T ≤ 100 K. b Normalized ab plane resistivity as a function of temperature, showing the \(-\ln (T)\) dependence at intermediate temperatures characteristic of the Kondo effect. The red dashed lines correspond to this logarithmic temperature dependence. The blue arrows point at the approximate value of TK, the Kondo temperature value is estimated as the temperature at which the resistivity deviates from the logarithmic behaviour. c Variation of the Kondo temperature estimated from the resistivity measurements as a function of the out of plane magnetic field μ0H = − 7 T…7 T, showing a small and symmetric variation around H = 0. The values shown are an average of repeated measurements and the error bars represent the standard error of the mean.
