In-Plane Electrical Resistivity in High Magnetic Fields and Stripe Order in La_2-xBa_xCuO₄ around x = 1/8: Implication for the Field-Induced Stripe Order
La_2-xBa_xCuO₄のx ~ 1/8における強磁場中面内電気抵抗率とストライプ秩序：磁場誘起ストライプ秩序の可能性

Magnetic-field effects on the so-called charge-spin stripe order in La_2-xBa_xCuO₄ around x = 1/8 have been investigated from the in-plane electrical-resistivity, ρ_ab, measurements. For x = 0.10, the superconducting transition curve changes from a broadening in low fields to a parallel shift in high fields above 9 T. Moreover, the normal-state value of ρ_ab at low temperatures markedly increases with increasing field up to 27 T. It is possible that these pronounced features of x = 0.10 are understood in terms of the magnetic-field-induced stabilization of the stripe order.
