Abstract

The rotational properties of M centers in alkali halides are investigated as a possible basis for storing information. Measurements using a NaF matrix indicate that high storage density, high writing efficiency, thermal stability, and nondestructive readout are attainable in a practical situation at room temperature or lower. However, temperatures below 300 K are necessary for fatigue-free operation in the present material.
