Abstract
A basic form of a variable capacitive apparatus and its actuating method are disclosed. The apparatus is a simple two-terminal structure and may be set by short duration, low voltage electrical pulses. Materials with perovskite structure or perovskite-related structures, especially colossal magnetoresistive materials, are the active constituents of the apparatus. The apparatus overcomes the shortcomings of its predecessors and offers the advantages of non-volatility, two or multi-level storage, non-destructive reading, free-of-power maintenance and potential high radiation hardness.
