概要

• 論文の詳細を見る

• RF properties of superconducting YBa_2Cu_3O_<7-x> were measured with the standing-wave method in the microwave region. The power absorption (Joule loss) of the powder specimen, calculated from the data of the voltage standing-wave ratio (VSWR), changes markedly at the transition temperature, and decreases with decreasing temperature in the superconducting state. In a lower temperature region, it tends to the formula A=17.6 exp (-0.031 eV/ kT). Microwaves were found to penetrate considerably into the superconducting specimen.
