摘要: Zero-field and longitudinal-field muon-spin-relaxation measurements have been carried out in order to investigate the electronic magnetic states La 2- x Sr CuO 4 over a wide range of hole concentration from =0.024 0.15. It has found that dynamic depolarization rate muon spins zero field starts increase monotonically with decreasing temperature at high around 100 K. This effect is enhanced 1/8 per Cu but easily suppressed by application small external couple ten gauss. The present study suggests dynamics fluctuating internal fields site normal state changes K correlated mobility holes. Possible relationships spin-hole stripes spin-gap are discussed.
