Abstract:
A device capable of storing information, comprising a new sulfide alloy embedded in a substrate, the alloy exhibiting a metal-semiconductor phase transition with hysteresis as a function of temperature and a positive temperature coefficient. In one embodiment of the device the bistable material may be represented by the formula Ba(Co. sub. 1-x Ni. sub. x)S. sub. 2-y, wherein x is between 0 and 1 and y varies from 0-2.
