Achievement of Curie transition to 330 K by Ba substitution in LaMnO3

Bending Modulated Ultralarge Magnetoresistance in Flexible La0.67Ba0.33MnO3 Thin Film Based Device

“…We argue that the uniaxial axis induced by mechanical bending can increase the Mn−O−Mn bond length which favors the double exchange interaction and hence tune the metal−insulator transition (MIT) temperature of the film. 19,27 For LBMO film, the MIT happens around room-temperature, which leads to strong relation between temperature and MR ratios. The different MR values along different directions arise from the different level of strain that along and perpendicular to the bending directions, respectively.…”

“…LBMO is a roomtemperature MR material with rhombohedral crystalline structure (a = b = 5.54 Å, c = 13.51 Å, α = β = 90°, γ = 120°). 27 We argue that the anisotropy in crystalline structure can induce strong AR in this system. Furthermore, the electronic strong correlation structure can endow the film with significant bending modulated performances.…”

“…Based on the flexible substrate, several kinds of perovskite oxides like La 0.67 Sr 0.33 MnO 3 , , La 0.67 Ca 0.33 MnO 3 , and SrRuO 3 , have been epitaxially grown with nice crystalline quality. LBMO is a room-temperature MR material with rhombohedral crystalline structure ( a = b = 5.54 Å, c = 13.51 Å, α = β = 90°, γ = 120°) . We argue that the anisotropy in crystalline structure can induce strong AR in this system.…”
