Theoretical study of the magnetic properties and the magnetocaloric effect in lanthanum manganite lacunar compounds

•The La1-xxMnO3 (x = 0.1 and 0.2) compounds was successfully prepared by sol-gel method.•The variation of (M) vs. (T) reveals a ferromagnetic to paramagnetic phase transition around TC.•A concordance with the experimental results is noted. Based on the Monte Carlo method and using the Ising model, t...
