摘要

A large single crystal (7 × 7 × 3 mm3) of YBa2Cu3O6.2 has been grown and its magnetic excitations have been observed by neutron-scattering techniques. A two-dimensional magnetic ridge, similar to that observed for La2CuO4-y, has been clearly identified by triple-axis measurements. The slope of the dispersion curve for spin-wave excitations is very large (0.5 eV), consistent with the result of spinpair Raman scattering by Lyons et al.
