Abstract

Magnetic-field effects on the charge-spin stripe order in La-214 high-Tc cuprates have been investigated from measurements of the in-plane electrical-resistivity, ρab. In La2-xBa xCuO4 with x 0.10 and La2-xSr xCuO4 with x 0.115 where the incommensurate charge peaks are weak and unobservable in zero field in elastic neutron-scattering measurements, respectively, the normal-state value of ρab at low temperatures markedly increases with increasing field up to 27 T. For La 2-xBaxCuO4 with x 0.11 and Zn-substituted La2-xSrxCu1-yZnyO4 with x 0.115 and y 0.02 where the charge stripe order is fairly stabilized in zero field, on the other hand, the increase in ñab with increasing field is negligibly small. In conclusion, when the charge-spin stripe order is not fully stable in zero field, magnetic field operates to stabilize the charge-spin stripe order. The value of ρab increases with increasing field depending on the stability of the charge stripe order.
