Summary:•Monte Carlo simulations give validation of experimental Curie temperature for Pr2FeCrO6.•Pr2FeCrO6 shows good magneto-dielectric response and magnetoresistance behavior.•These results are promising to use Pr2FeCrO6 for spintronics applications. Evidence for Curie temperature (TC = 550 K) in the double perovskite Pr2FeCrO6 is resuscitated with Monte Carlo simulations, temperature dependence of resistivity and dielectric constant. It is concluded that Curie temperature of Pr2FeCrO6 is 550 K in R 3 symmetry. Magnetoresistance measurement in Pr2FeCrO6 at room temperature shows a value of 44%. All these results confirm the expediences of using Pr2FeCrO6 materials in multiferroic-based magnetic tunnel junctions for spintronics applications.
