Title: Complex Permittivity Measurements of Single-Crystal and Ceramic Strontium Titanate at Microwave Frequencies and Cryogenic Temperatures
Published: May 01, 2000
Abstract: The permittivity and dielectric loss tangent of bulk strontium titanate were measured from 4 to 3pp K, at frequencies from 400 MHz to 3.8 GHz, using a dielectric rod-resonator technique. Single-crystal and ceramic SrTiO3 samples were both investigated. Significant differences in permittivity and losses were observed between single-crystal and ceramic materials at cryogenic temperatures. When measured at liquid nitrogen temperatures, the single-crystal sample dielectric loss tangent was approximately 10-4.
