摘要： The invention relates to an electric element, whose conductance is quantized in units 2e.sup.2 /h realized in a multi-dimensional charge carrier gas, which is provided with a part of reduced width having a width of the order of the Fermi wavelength and a length smaller than the average free path length. Due to the small width of the part of reduced width, the energy levels are subdivided, as a result of which, at a temperature at which the distance between the levels is comparable with kT, the charge transport through the constriction is determined by quantum-mechanical effects. For the charge carrier gas, for example, a two-dimensional electron gas near a GaAs-AlGaAs hetero-junction may be used, for example, in a voltage divider.

摘要： A magnetic multilayer device (1) comprising two layers (3, 5) of magnetic material which are separated by an interposed layered structure comprising a resonant-tunneling double-barrier structure (RTDBS) (7). In such a device (1), exchange coupling between the magnetic layers (3, 5) can be modified by subjection of the RTDBS (7) to an electric field. In this way, the configuration of the magnetisations (M.sub.1, M.sub.2) in the magnetic layers (3, 5), and thus the net magnetic flux generated by the device (1), can be electrically adjusted. The device (1) can be applied inter alia in a magnetic recording head.
