“…Magnetic refrigeration is a technique that is based on the magnetocaloric effect. The principle is the heating or cooling of materials with application or supression of magnetic eld [16][17][18][19][20]. It's important note that the Gd is the best magnetic refregerant at room temperature formagnetic refregeration [21][22].…”

Structural, magnetic, magnetocaloric and thermoelectricproperiesLa0.9†0.1MnO2.9 wereexamined in this original paper. Indeed, the structural study demonstrated that this compound crystallized in the rhombohedric system with R-3c space group. The magnetization in terms of temperature corroborated the PM-FM transition when temperature decreased. The fit of hysteresis cycle at 5 K FM showed a domination of the FM contributions. Subsequently a magnetic entropy change deduced from the isothermal magnetization curves was observed in our samples with a peak centered on their Curie temperature (TC). The total electronic density states (TDOS) prove the coexistence of metallic behavior for spin up states and semiconductor characteristic with a Eg = 1.3 eV for spin down states. Thermoelectric properties analysis revealed promising behavior, with ZT reaching 1.1 at 420 K
