Is there an incommensurate magnetic resonance in La2-xSrxCuO4?

Most optimally-doped high- Tc cuprate superconductors show a magnetic excitation (known as the 'resonance') at q=(pi,pi ) whose intensity increases sharply below Tc. This...绝大多数最佳掺杂高温铜基超导体（high-Tc cuprate superconductors）会在波矢q=(π,π)处呈现出被称为"共振"的磁激发（magnetic excitation），其强度在低于临界转变温度Tc时会急剧升高。
