Abstract

Photochemical holeburning storage is a low temperature technology because only near liquid helium temperatures are hole widths narrow enough (i.e., N300 MHz) to be practically useful. All materials for this application that are known so far lose their information if they are warmed to room temperature and then returned to low temperature for reading. This volatility is undesirable in the event of refrigeration failure. Thus, a class of materials which would be capable of room temperature cycling without information loss is needed. A method has now been found for efficiently identifying materials which have this capability. An example of such a material is BaClF: Sm2+.
