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.
