Evidence of substrate induced charge order quenching, insulator metal transition, and colossal magnetoresistance in polycrystalline Pr0. 58Ca0. 42MnO3 thin films
We report the magnetoelectrical properties of polycrystalline Pr 0.58 Ca 0.42 MnO 3 thin
films (thickness∼ 300 nm) deposited on single crystal LaAlO 3 (LAO) and SrTiO 3 (STO)
substrates. The films on LAO show charge ordering (CO) at T CO≈ 240 K, with a
metamagnetic ground state akin to the cluster glass (CG). In PCMO/STO films the CO is
quenched and enhanced magnetic moment in the CG state suggests stronger ferromagnetic
component. The resistivity of the films on LAO and STO differ drastically, the former has …
