Abstract
Magnetic device for domain propagation, which allows certain magnetic materials having useful polarization field ranges in the restricted temperature ranges hitherto to be used to support the activity of the single transition layer domain; the magnetic arrangement comprising means for providing a bias field (26, Figure 1; 51-54, Figure 5); and a layer (11) of material in which single transition layer domains can be moved in response to a propagation arrangement (25), whose domains are stable in the material only at operating temperatures in a first range in the presence of a polarization field (HB) of one polarity to constrain the domains, whose layer has a negative value polarization field range (-HB, figure 4) in a second temperature range outside said first temperature range characterized in that the bias field provided by the means to provide a bias field (26, Figure 1; 51-54, Figure 5) varies as a function of the temperature in said first and second temperature ranges in essentially the same way as the layer of material (11) that supports the activity of the domain transition layer.
