Effect of Fe substitution on magnetocaloric effect in La0.7Sr0.3Mn1−xFexO3 (0.05≤x≤0.20)

Effect of strontium deficiency on the structural, magnetic and magnetocaloric properties of La0.65Eu0.05Sr0.3−xMnO3 (0 ≤ x ≤ 0.15) perovskites

“…Hence, the presence of mixed valence states of Mn ions in the doped manganites gives rise to the competing double exchange (DE) and super-exchange (SE) interactions. [17][18][19][20] On the other hand, the ceramic preparation route, such as the conventional solid-state reaction method, the sol-gel method and combustion thermal spray techniques were used to prepare rare-earth perovskite materials. [10][11][12][13] The manganites have additional advantages such as low cost, good chemical stability, easy preparation and more importantly the ability to tailor their magnetic transition temperatures close to room temperature by R-site or Mn-site substitution.…”

Effect of Al substitution on magnetocaloric effect in La0.57Nd0.1Sr0.33Mn1−xAlxO3 (0.0≤x≤0.30) polycrystalline near room temperature

“…In fact, it has been revealed that La 1−x Sr x MnO 3 based manganite materials, modulated by Mn-site substitution with Cr, Cu, Ni, Co, Fe etc., present a large isothermal entropy change upon an application of a magnetic field around the ordering temperature T C [18][19][20][21].…”

Crystal structures and magnetic properties of strontium and copper doped lanthanum ferrites

“…This is motivated also because the correlation that exists with possible multiferroic [27] or magnetocaloric [38] properties are receiving large attention [39].…”
