BROADBAND ZERO FIELD EXCHANGE ECHO SYSTEM

摘要

A system for the generation of an "exchange echo" signal similar to a spin echo signal utilizing a very heavily doped sample such as rutile, having paramagnetic defect centers in the order of 1 x 1019 to 1 x 1021 defect centers/cm, wherein no magnetic field of any kind is necessary for the production of the echo signals, and wherein echo bandwidths considerably greater than those generally associated with spin echoes (less than 300 MHz) are achievable.
