Pressure induced semiconductor-like to metal transition and linear magnetoresistance in CrSsingle crystal.

The transition metal chalcogenide CrShas unique properties, such as a lower antiferromagnetic transition temperature, semiconducting behavior, and thermoelectric properties. We focus on the effects of high pressure on the properties of electrical transport and structure in the single crystal CrS. It is observed that the resistance drops abruptly by approximately two orders of magnitude and the temperature derivative of the resistance changes from negative to positive after 15.
