Exchange bias in an oxide heterostructure without an antiferromagnet is attributed to a magnetoelectric coupling mediated by skew scattering and orbital angular momentum in the LaAlO3 valence band.
Therefore, the localized form of a dipo- lar magnetic field [25] can be used to estimate I = µ2 Bµ0/3ℏ ≈ 2.14 eV
