Abstract: A method for reconfiguration of a vortex density in a rare earth manganate, to a non-volatile impedance switch having reconfigurable impedance, and to the use thereof as micro-inductance is disclosed. A unique voltage-time profile is applied between a first and a second electrically conductive contact attached to the rare earth manganate, such that the rare earth manganate passes through an ordering temperature in a region of an electric field forming between the two electrically conductive contacts during a cooling process during and after application of the voltage pulse or the voltage ramp, and the vortex density is thus influenced and adjusted locally in the region of the electric field forming between the two electrically conductive contacts.

Abstract: A capacitance diode or variable capacitance diode includes first and second electrodes and a layer configuration disposed in contact-making fashion between the two electrodes. The layer configuration has, one after the other in a direction from the first electrode towards the second electrode, a layer formed of a ferroelectric material and an electrically insulating layer formed of a dielectric material having electrically charged defects. A method for producing a capacitance diode or a variable capacitance diode, a storage device and a detector including a capacitance diode or a variable capacitance diode are also provided.
