Mechanical after-effect studies of oxygen relaxation in YBa(sub 2)Cu(sub 3)O(sub 7-(delta)).

摘要

YBa(sub 2)Cu(sub 3)O(sub 7(minus)(delta)) has an anelastic relaxation involving motion of an oxygen atom or defect. This relaxation has been studied with good agreement by more than seven investigating teams over the temperature range from 200 to 550(degr ...
