Transport and photoinduced properties in La0.8Sn0.2MnO3 thin film

Studies on La0.67Ca0.33MnO3–SrTiO3 composites using two-phase model

“…For a better understanding of CMR a large number of studies have been carried out in single crystals [6], thin films [7,8], polycrystalline CMR materials [9,10] and CMR-based composites [11][12][13][14][15][16][17][18]. Many groups have attempted to synthesize CMR-insulator composites, such as La 0.67 Ca 0.33 MnO 3 (LCMO)-MgO [11], LCMO-BaTiO 3 (BTO) [12,13], LCMO-Al 2 O 3 [14,15], La 0.67 Sr 0.33 MnO 3 -La 2 O 3 -La(OH) 3 [16], La 0.67 Sr 0.33 MnO 3 -polyaniline [17] and LCMO-SrTiO 3 (STO) [18], etc.…”

Review of photoinduced effect in manganite films and their heterostructures

“…For the manganite systems with the typical metalinsulator transition, the photo-irradiation results in an increase of the resistivity of the film in the metallic state and a decrease in the insulating state. [53][54][55][56][57][58] Generally, the light can excite the downspin e g electrons, which will destroy the ferromagnetic coupling between the upward-spin e g and t 2g electrons in Mn 3+ ions. As a result, it weakens the double exchange effect and increases the resistivity.…”
