摘要：

The first direct observation by inelastic neutron scattering of spin-phonon coupling for a dilute paramagnetic system Cr2+ in MgO, is reported. The enhancement of phonon linewidths and the absence of significant dispersion near the resonant frequency is shown to be evidence for critically coupled" modes. © 1979 The American Physical Society."
