• The internal friction and compliance of YBa_2Cu_3O_<7-x> are measured at temperatures from 300 to 1050K using a LiNbO_3 composite oscillator technique. An anelastic relaxation due to oxygen movement at 80-200 kHz is observed to be associated with the orthorhombic-to-tetragonal (O-T) phase transition in YBa_2Cu_3O_<7-x> at 850-900 K. By careful fitting for the measured internal friction against temperature, we provide data on the relaxation time and peak temperature in the highest frequency region for a linear Arrhenius plot that extends over 7 orders of magnitude.
