4 p, 70.8 KB Coercivity enhancement in exchange biased systems driven by interfacial magnetic frustration / Leighton, C. (University of California, San Diego. Department of Physics) ; Nogués, Josep (Universitat Autònoma de Barcelona. Departament de Física) ; Jönsson-Akerman, B. J. (University of California, San Diego. Department of Physics) ; Schuller, Ivan K. (University of California, San Diego. Department of Physics) ; American Physical Society
We report the temperature and cooling field dependence of the coercivity of exchange biased MnF2/Fe bilayers. When the antiferromagnetic surface is in a state of maximum magnetic frustration and the net exchange bias is zero, we observe a strong enhancement of the coercivity, which is proportional to the exchange coupling between the layers.

An approach to compute the polarizability tensor of magnetic nanoparticles having general ellipsoidal shape is presented. We find a surprisingly excellent quantitative agreement between calculated and experimental magneto-optical spectra measured in the polar Kerr configuration from nickel nanodisks of large size (exceeding 100 nm) with circular and elliptical shape.

Nanostructured Mn67Ga33 films exhibiting high room temperature coercivity (HC = 20. 5 kOe) have been prepared by sputtering onto thermally oxidized Si substrates. Both the morphology and the coercivity of the films can be tuned by varying the growth parameters. [...]
