چکیده
Ni0.95Fe0.05/NiFeO multilayers were fabricated by radio frequency magnetron sputtering and natural oxidation. Doping of Ni only 5 at. % Fe results in enhanced layering quality as X-ray reflectivity reveals. Due to magnetostatic anisotropy, the found be in-plane magnetized. The influence mild thermal annealing (T = 525 K) on magnetic properties NiFe/NiFeO is also investigated. Annealing enhancement perpendicular mainly due an increase uniaxial volume anisotropy term. Temperature-dependent hysteresis measurements between 4–400 K revealed considerable coercivity appearance exchange bias effect.

Exchange bias in thin-film (Co/Pt)3/Cr2O3 multilayers
We have fabricated exchange-biased Co/Pt layers ((0.3 nm/1.5 nm) 3) on (0 01)-oriented Cr2O3 thin films. The multilayered films showed extremely smooth surfaces and interfaces with root mean square roughness of E0.3 nm for 10mm 10mm area. The Cr2O3 films display sufficient insulation with a relative low leakage current (1.17 10 A/cm at 380MV/m) at room temperature which allowed us to apply elec...

متن کاملExchange Coupling in Magnetic Multilayers
In magnetic multilayers, the magnetizations of two ferromagnetic layers separated by a non-magnetic spacer layer are coupled by the electrons in the spacer layer. This coupling oscillates in sign as a function of the thickness of the spacer layer. Extensive research done on these systems has led to a simple model for this coupling and remarkable agreement between predictions of the model and me...
متن کاملCoercivity and exchange bias of ferromagnetic/antiferromagnetic multilayers
For a model system consisting of a ferromagnetic layer exchange coupled to an antiferromagnetic layer with a compensated interface, detailed mean-field-type calculations are performed. Both the coercive field and the exchange bias field are calculated. For the coercive field, a rather broad enhancement around the Néel temperature TN of the antiferromagnetic layer is found irrespective of whethe...
متن کاملCompeting anisotropies in exchange-biased nanostructured thin films
The magnetic anisotropies of a patterned, exchange biased Fe50Mn50/Ni80Fe20 system are studied using ferromagnetic resonance, supplemented by Brillouin light scattering experiments and Kerr magnetometry. The exchange biased bilayer is partially etched into an antidot geometry so that the system approximates a Ni80Fe20 layer in contact with antidot structured Fe50Mn50. Brillouin light scattering...
