Abstract

One way to obtain new information about the ubiquitous low-lying two-level systems found in glasses is to identify them in appropriately modified crystals and then vary the crystal properties. Here our low-temperature mm-wave absorption and Raman scattering measurements on a number of mixed fluorite crystals are reviewed. It is shown that these single-crystal materials possess a broad distribution of two-level systems similar to what is found in the amorphous state.
