Abstract

Magnetic-field effects on the so-called charge-spin stripe order, namely, the charge stripe order and spin stripe order in the La-214 system have been investigated from the in-plane electrical-resistivity, ρab, measurements. In La2-xBaxCuO4 (LBCO) with x = 0.10 and La2-xBaxCuO4 with x = 0.115 where the incommensurate charge peaks are weak and unobservable in zero field from the elastic neutron-scattering measurements, respectively, the normal-state value of ρab at low temperatures markedly increases with increasing field up to 27 T. As for x = 0.11 in LBCO where the charge stripe order is fairly stabilized in zero field, the increase in ρab with increasing field is negligibly small. In conclusion, the magnitude of the increase in ρab by the application of magnetic field is well correlated with the stability of the charge stripe order in zero field for the La-214 system around x = 1/8. Our understanding is as follows. 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.
