Oxygen stoichiometry-driven charge compensation and Ruddlesden–Popper defects in ferromagnetic high-entropy manganite thin films

Communications Materials
High-entropy oxides (HEOs) originate from an innovative materials design strategy that stabilizes single-phase solid solutions despite the inclusion of multiple principal elements into a single cation sublattice.

Spin-lattice relaxation phenomena in manganite La0.7Sr0.3MnO3 thin films

, 2006
Time-resolved magneto-optics was used to study spin-lattice relaxation dynamics in thin epitaxial La0.7Sr0.3MnO3 films. Two distinct recovery regimes of the ferromagnetic order can be resolved upon photoexcitation, which manifest themselves by two ...

Effects of interaction and disorder on polarons in colossal resistance manganite Pr0.68Ca0.32MnO3 thin films

Materials Research Express, 2014
The colossal magnetoresistance effect (CMR), the drop of the electric resistance by orders of magnitude in a strong magnetic field, is a fascinating property of strongly correlated electrons in doped manganites.

Planar spin valves fabricated on manganite epitaxial thin films

, 2006
We fabricate micrometric constrictions in manganite epitaxial thin films by atomic force microscope local anodization. We demonstrate the possibility of realizing planar spin valve devices, exhibiting hysteretic transport behavior as a function of the ...

The Effects of Strain on The Magnetic Anisotropy of Doped Manganite Thin Films

, 1997
We show the importance of the role of strain in doped manganite perovskite materials by revealing the dominance of stress anisotropy effects over magnetocrystalline anisotropy effects in the magnetic anisotropy of these films.
