Abstract

Magnetic measurements on a high-T_c superconductor YBa ₂Cu₃O₇ reveal new spin-glass-like features. At low temperatures and low fields the irreversible part of the field-cooled magnetization M_irr rotates with the sample as a rigid entity. The rigidity is broken and part of M_irr disappears above an angle φ* which decreases with increasing temperature or field. This behavior resembles that of spin glasses and differs qualitatively from the behavior found for Nb.
