ZERO-FIELD NMR IN CUMN - NEW VIEWPOINT ON REMANENCE IN SPIN-GLASSES

Zero-field Cu NMR of the first and fourth nearest neighbors of Mn in spin-glass Cu-Mn(1%) have been detected for TTg5. The observed enhancement of rf field and signal intensity, associated with domain rotation, increases with the remanent magnetization and vanishes if the sample is zero-field cooled. A new description of the remanent properties of spin-glasses with no independent magnetic domains after zero-field cooling is proposed. © 1979 The American Physical Society.
