Abstract
We have utilized the antiferromagnetic nature and structural/chemical compatibility of La0.45Sr0.55MnO3 with highly spin polarized La0.67Sr0.33MnO3 to prepare epitaxial exchange bias (EB) couples. A robust EB shift in magnetization hysteresis with associated interfacial exchange energy J ≈ 0.13 erg/cm2 at 10 K along with enhanced coercivity is reported. The EB effect was engineered to bring coercivity contrast between La0.67Sr0.33MnO3 and cobalt films in La0.45Sr0.55MnO3/La0.67Sr0.33MnO3/SrTiO3/Co magnetic tunnel junctions.
