  journal={Physical Review B},
Exchange bias has been studied in a series of ${\text{La}}_{2/3}{\text{Ca}}_{1/3}{\text{MnO}}_{3}/{\text{La}}_{1/3}{\text{Ca}}_{2/3}{\text{MnO}}_{3}$ bilayers grown on (001) ${\text{SrTiO}}_{3}$ substrates by ozone-assisted molecular-beam epitaxy. The high crystalline quality of the samples and interfaces has been verified using high-resolution x-ray diffractometry and $Z$-contrast scanning transmission electron microscopy with electron-energy-loss spectroscopy. The dependence of exchange bias…

Evidence of a 7 nm-thick interface layer in La0.7Sr0.3MnO3 (LSMO) thin films is obtained, for the first time, and a structural shift of Mn ions coupled with oxygen vacancies and a reduced Mn valence state within such layer is observed.
Interface-induced spontaneous positive and conventional negative exchange bias effects in bilayer La0.7Sr0.3MnO3/Eu0.45Sr0.55MnO3 heterostructures
The isothermally field induced unidirectional exchange anisotropy formed at the interface of FM-LSMO layer and the kinetically phase-arrested magnetic phase obtained from the metamagnetic AF-ESMO layer could be responsible for the spontaneous exchange bias effect.
