Magnetic hysteresis loops, corrected for the paramagnetic substrate of volume , measured at along the three perpendicular ⟨100⟩ orthorhombic directions of a LCMO41 film. The similarity between these three loops (and others taken in intermediate orientations) demonstrates the absence of magnetic anisotropy.

Magnetic and electrical measurements vs applied magnetic field for the trilayer at . (a) Magnetization, corrected for the paramagnetic substrate of volume , for the in-plane orthorhombic [100] direction. Easy axis switching of the top and bottom layers appears to be independent of the isotropic middle layer. (b) Current-in-plane resistance obtained at a measurement current of . At all measurement fields, curves were linear up to this current. The sharp switching corresponds to magnetic reversals of the bottom LCMO30 layer. No corresponding switch is seen for reversals of the top LCMO30 layer. The hysterestic regimes in (a) and (b) persist out to the same applied field.
