Title: Magnetic and electronic properties of La{sub 0.7}Ca{sub 0.3}MnO{sub 3}/h-YMnO{sub 3} bilayer

La{sub 0.7}Ca{sub 0.3}MnO{sub 3}/h-YMnO{sub 3} (h ∼ hexagonal) bilayer thin films are grown using pulsed laser deposition technique and magnetic/band-offset measurements are performed to explore the magnetic/electronic properties. The bilayer displays the signatures of the ferromagnetic (FM) La{sub 0.7}Ca{sub 0.3}MnO{sub 3} layer and antiferromagnetic (AFM) h-YMnO{sub 3} layer. The uncompensated spins at the interface of FM/AFM layers caused exchange bias effect. The vertical and horizontal shift in field cooled isothermal magnetization curves below the AFM transition temperature shows dependence on the sign of the cooling magnetic field. Type-II band alignment at the interface of bilayer is realized through valence band offset and conduction band offset values estimated from the photoemission results.
