The exchange bias e!ect is measured for the "rst time in FeF 2 }CoPt heterosystems with perpendicular anisotropy. The exchange "eld exhibits a strong dependence on the axial freezing "eld. This behavior is explained in terms of the microscopic spin structure at the interface, which is established on cooling to below 1 N . We calculate the dependence of the spin structure on the freezing "eld wi...

Polycrystalline MgO underlayer films lead to different preferred orientations of 10 CoPt and FePt films after the annealing process, depending on the thickness of 10 films. 10 films with a thickness greater than 20 nm revealed mostly 10 [100] fiber texture and consequently in-plane anisotropy as determined by magnetic hysteresis. Strong perpendicular anisotropy due to the 10 [001] fiber texture...

The possibilities of controlled exposure to ion irradiation (He+ with an energy 20 keV and a fluence in the range from 3×1014 3×1015 cm–2) as method for modifying magnetic properties domain structure Co0.35Pt0.65 thin ferromagnetic films have been studied. It was found that causes change Dzyaloshinsky-Moriya interaction constant skyrmion density correlates it. This result shows possibility homo...

A new method for selecting controlled variables (c) as linear combination of measurements (y) is proposed based on the idea of self-optimizing control. The objective is to find controlled variables, such that a constant setpoint policy leads to near optimal operation in the presence of low frequency disturbances (d). We propose to combine as many measurements as there are unconstrained degrees ...
