PrSb is a kind of monoclonal antibody RSb compound with intruguing properties, such as topological nontrivial surface state and extremely large magnetoresistance. High pressure is a clean and powerful means of tuning the ground state of a material and generate new phases. Here we present a systematic high pressure transport study on PrSb single crystal samples. We find that a peak appears suddenly at about 23 K at P = 2.52GPa. With the increase of pressure, the peak moves to the high temperature region. This characteristic is basically consistent with the theoretical prediction of antiferromagnetic phase transition in PrSb. Based on our data, we constructed the temperature-pressure phase diagram of PrSb.
