“…1 Small magnetic and thermal hysteresis can disregard the presence of losses in the performance and cycle reversibility of the MCE properties in MRT. Examples of materials exhibiting SOMT behavior include La 0.55 Ca 0.05 Sr 0.40 MnO 3 , 60 La 0.05 Pr 0.1 Sr 0.35 MnO 3 , 61 Zn 0.6 Cu 0.4 Fe 2 O 4 , 62 CoGa 1.2 Fe 0.8 O 4 , 36 and others.…”

“…This is marked by a significant decrease in magnetization around T C as many research results. 20,60,115 To determine T C value more accurately, an analysis of the phase transition temperature is needed, where the determination is done by deriving M – T to temperature (d M /d T ). The analysis for determining the T C value was also conducted by Munazat et al , stating that the T C values for La 0.7 Ba 0.1 Ca 0.1 Sr 0.1 MnO 3 samples are 330.81 K and 316.17 K for SG and WM samples, respectively.…”

The structural characterization, and the electronic, magnetic and magnetocaloric properties of polycrystalline samples of La 0.7 Ca 0.3 Mn 1¹x Cu x O 3 (x = 0, 0.04, 0.06, 0.08) have been investigated. X-ray powder diffraction analysis indicates all samples having an orthorhombic structure, belonging to the Pbnm space group. X-ray absorption fine structure spectra reveal that Mn is in the mixed state of Mn 3+ and Mn 4+ while Cu has divalent state (Cu 2+ ). With the substitution of Cu 2+ for Mn, the Curie temperature, T C , decreases monotonically from 248 K for x = 0 to 156 K for x = 0.08, which is due to weakened exchange interactions. The downturn in the temperature dependencies of the inverse magnetic susceptibility, » ¹1 (T ), curves observed above T C for x = 0 and 0.08 is characteristic of the Griffiths-like phase. The analysis of isothermal magnetization data M(T, H ) based on the Banerjee's criteria has indicated x = 0, 0.04, and 0.06 samples undergoing a first-order magnetic phase transition. However, the x = 0.08 sample, the coexistences of second-order magnetic phase transition at low magnetic fields below 8 kOe and first-order magnetic phase transition at high magnetic fields were observed. The maximum magnetic entropy change measured at a magnetic field span of 50 kOe occurring near the T C decreases from 10.3 to 4.8 J/kg.K with increasing x from 0 to 0.08. However, the relative cooling power (RCP) tends to increase, in which a maximum RCP of 360 J/kg for x = 0.08 that is about 1.3 times greater than that observed for the parent sample (x = 0).
