Epitaxial growth and electric/magnetic properties of a magneto-electric Cr2O3 thin film

We have investigated the epitaxial growth and the electric/magnetic properties of magnetoelectric material: a Cr 2 O 3 thin film. The epitaxial growth mode of Cr 2 O 3 was changed from 2- to 3- dimensional at a temperature around 500 °C. Although Cr 2 O 3 is antiferromagnetic, the epitaxial Cr 2 O 3...

Zusammenfassung:We have investigated the epitaxial growth and the electric/magnetic properties of magnetoelectric material: a Cr 2 O 3 thin film. The epitaxial growth mode of Cr 2 O 3 was changed from 2- to 3- dimensional at a temperature around 500 °C. Although Cr 2 O 3 is antiferromagnetic, the epitaxial Cr 2 O 3 showed ferromagnetic hysteresis. Because the magnetic behavior showed perpendicular anisotropy, the epitaxial compressive stress is responsible for the ferromagnetic behavior. The film also showed a polarization change even with the application of a small magnetic field. This revealed that the epitaxial stress could affect the magneto-electric properties of Cr 2 O 3 .
