摘要: The normal-state magnetotransport properties of ${\mathrm{La}}_{2\ensuremath{-}x}{\mathrm{Ba}}_{x}{\mathrm{CuO}}_{4}$ single crystals with $x=0.095$ are measured; at this composition, a structural transition to low-temperature tetragonal (LTT) phase occurs without suppression superconductivity. None the measured (in-plane and out-of-plane resistivity, magnetoresistance, Hall coefficient) shows any sudden change LTT transition, indicating that occurrence does not necessarily cause an immediate in electronic state such as charge-stripe stabilization.
