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=(1/2,1/2) whose intensity increases sharply on cooling below Tc....绝大多数最佳掺杂的铜基高温超导体（high-Tc cuprate superconductors），在倒格矢q=(1/2,1/2)处存在一种被称为“共振”的磁激发，其强度在冷却至超导临界温度（Tc）以下时会急剧升高。
