    • Magneto-caloric effect in Pb$_2$CoUO$_6$ with the second-order phase transition


      More Details Abstract Fulltext PDF

      Theoretically, the magnetic behaviours and the magneto-caloric performance of the Pb$_2$CoUO$_6$ double perovskite were predicted and examined. The results attained in this paper showed that the Pb$_2$CoUO$_6$ double perovskite was a ferromagnetic state under Tc${\sim}$10 K. The order magnetic transition of this system was a second-order from the ferromagnetic (FM) to the paramagnetic (PM) transition above $T$$_c$. The Pb$_2$CoUO$_6$ double perovskite was a hard magnetic material. Additionally, other physical quantities were determined and examined; namely, the magnetic entropy change(-${\Delta}$$S$$_M$) and the relative cooling power (RCP), which were 4.38 J kg$^{-1}$ K$^{-1}$ and 25.47 J kg$^{-1}$, respectively, at the applied magnetic field of 4 T. All these physical quantities were examined using the Monte Carlo approach (MCA).
