Morphology, magnetic and magnetocaloric properties of La 0.62 Er 0.05 Ba 0.33 Mn 1−x Fe x O 3 (x = 0.00, 0.05 and 0.15) were experimentally investigated. Solid-state reaction method was used in the preparation of the samples. The microstructure of the samples was determined by scanning electron microscopy (SEM). From the XRD study, it has been found that all samples are single-phased and crystallized in the rhombohedral structure with the R3-c space group. For x = 0.05 and 0.15, a steep drop of zero field-cooled (ZFC) magnetization at low temperature signifies the formation of cluster-or spinglass state. This is caused by the competition between the ferromagnetic and antiferromagnetic interaction. A sensitive response to substituting Fe for Mn is observed in the magnetic and magnetocaloric properties. We found that Fe doping is powerful enough to reduce Curie temperature T C and it brings about cluster glass behaviours. The magnetocaloric effect is calculated from the measurement of initial isothermal magnetization versus magnetic field at various temperatures. The maximum entropy change S max M reaches the highest values of 3.31, 3.12, and 2.57 J/kg K in magnetic field. However, the relative cooling power decreases with Fe content from x = 227.44 to 188.68 J/kg for x = 0.00 to x = 0.15 compositions, respectively.

“…Moreover, the properties of these manganites are usually explained by the double exchange (DE) interaction, which considers the coupling between the trivalent (Mn 3+ ) and tetravalent (Mn 4+ ) ions. These materials have unusually strong coupling among their lattices, spins and charge degrees of freedom [11,12], which make them more complex and DE mechanism alone cannot explain all physical properties in the CMR materials [13,14].…”

“…Recently we have investigated La 0.67 Ba 0.33 Mn 1-x TM x O 3 systems with TM=Ti 4+ [7] and Fe 3+ [8]. The effect of trivalent magnetic (Fe 3+ ) or tetravalent non-magnetic (Ti 4+ ) substitution for Mn on magnetic and electrical properties [7][8][9] appears quite similar in both systems and eliminates the ferromagnetic/metallic (FM/M) and paramagnetic/ insulator (PM/I) transitions in these systems. More recently we have shown that the Pr 0.67 Ba 0.33 Mn 1-x Fe x O 3 iron doped systems presents very interesting magnetocaloric properties [10].…”

Abstract. Changes in the physical properties of ceramic Pr 0.67 Ba 0.33 Mn 1-x Fe x O 3 (0 ≤ x ≤ 0.15) are interpreted as resulting from the suppression of the ferromagnetic double exchange interaction with almost no lattice effect due to similar ionic radii value of Fe 3+ and Mn 3+ Magnetization and transport measurements show at low temperature ferromagnetic and metallic behavior for x=0 and 0.05 samples, whereas x = 0.10 and x = 0.15 compounds show spin glass like and semiconducting behavior. At high temperature semiconductor and paramagnetic behavior are observed for all the samples.
