Intermetallic Gd3Ni2 and Gd3CoNi undergo second-order ferromagnetic paramagnetic phase transition at the Curie temperature, TC. They exhibit a large magnetocaloric effect (MCE). This MCE is manifested with a high entropic peak of 8 and 8.3 J.Kg−1 K

In this work, we used the mean-field theory (MFT) to estimate the spontaneous magnetization Mspont(T) from the dependence of magnetic entropy change on magnetization, $$- \Delta S_{M}$$ vs. M2 in Gd3Ni2 and Gd3CoNi systems. The obtained Mspont(T) val

In this paper, we exploited the mean field model to simulate the magnetocaloric effect (MCE) in Nd0.55Sr0.45MnO3 manganite which undergoes second-order ferromagnetic (FM)-paramagnetic (PM) phase transition. A scaling method, based on mean field theor

In this paper, we have used the Landau theory to simulate the MCE in the Nd0.67Ba0.33MnO3 manganite. The expanding of the Gibb’s free energy as a function of magnetization to the eighth order has given better results than the developing at sixth or

The magnetocaloric properties for double perovskite oxides Sr2−xGdxFeMoO6 with x = 0, 0.06, 0.1, 0.15, 0.2, and 0.25 under 0.05 T magnetic field have been theoretically investigated by using a phenomenological model. It has been noted that the Gd d
