Abstract

Storage and impedance switching in different circuit arrangements is obtained by utilization of an element made of ceramic materials consisting of a barium titanate ferrite, a perovskite, having the empirical formula Ba (Fe(x)Ti(1-x)) O(3), where x is restricted to a value between 0.75and 0.95.

An Induced Diode Effect

Storage and impedance switching in different circuit arrangements is obtained by utilization of an element made of ceramic materials consisting of a barium titanate ferrite, a perovskite, having the empirical formula Ba (Fe(x)Ti(1- x)) O(3), where x is restricted to a value between 0.75and 0.95.

An element 10 having the ceramic material described above of a thickness of 25 mils is located intermediate two gold electrodes which are 1/4" in diameter. With the switch SW at 1 the element is subjected to a field of 100 volts of the indicated polarity. When S/w/ is moved to 2 the high potential is removed and a much smaller potential of similar polarity is applied to 10. This results in very small current flow through 10. Moving S(w) to 3 applies a small potential of reversed polarity to 10 and results in relatively high current flow through 10. If the polarities of the three batteries are reversed the same phenomena occurs with regard to element 10, except the direction of current flow is reversed.
