Özet

The magnetic properties of La_1-xNd_xMn ₂Si₂ (x = 0.30-0.45) compounds are studied over the temperature range 5 K ≤ T ≤ 375 K. We report inverse and conventional magnetic entropy change values of La_1-xNd_xMn ₂Si₂ (x = 0.35 and 0.40) compounds over the temperature range 5 ≤ T ≤ 375 K. In addition, we study critical behavior of La _1-xNd_xMn₂Si₂ (x = 0.35 and 0.40) compounds around their Curie temperatures. The field dependence of the magnetic entropy change is brought out and implemented to deduce the critical exponents. The critical behavior study shows that the magnetic interactions for the x = 0.35 sample have the same behavior below and above T_C. However, for the x = 0.40 sample has different behavior below and above T_C. Thus, the x = 0.40 sample behaves as a multiphase compound.
