“…Could there be some sort of inhomogeneity in the samples that causes the ρ and ρ ⊥ measurements to be determined by distinct phases? Before addressing this question, we point out that the phase boundary for superconducting order determined by our ρ ⊥ data is quantitatively consistent with results in the literature 15,[19][20][21]43,44 for LSCO and LBCO with x ∼ 0.1. It follows that only the behavior of ρ is anomalous.…”

We present an experimental study of the anisotropic resistivity of superconducting La2−xBaxCuO4 with x = 0.095 and transition temperature Tc = 32 K. In a magnetic field perpendicular to the CuO2 layers, H ⊥ , we observe that the resistivity perpendicular to the layers, ρ ⊥ , becomes finite at a temperature consistent with previous studies on very similar materials; however, the onset of finite parallel resistivity, ρ , occurs at a much higher temperature. This behavior contradicts conventional theory, which predicts that ρ ⊥ and ρ should become finite at the same temperature. Voltage vs. current measurements near the threshold of voltage detetability indicate linear behavior perpendicular to the layers, becoming nonlinear at higher currents, while the behavior is nonlinear from the onset parallel to the layers. These results, in the presence of moderate H ⊥ , appear consistent with superconducting order parallel to the layers with voltage fluctuations between the layers due to thermal noise. In search of uncommon effects that might help to explain this behavior, we have performed diffraction measurements that provide evidence for H ⊥ -induced charge and spin stripe order. The field-induced decoupling of superconducting layers is similar to the decoupled phase observed previously in La2−xBaxCuO4 with x = 1/8 in zero field.

“…In fact, the dynamical stripe correlations are statically stabilized by the application of magnetic field parallel to the c-axis. [47][48][49][50] On the other hand, the magnetic order induced by the Fe substitution in the overdoped regime involves following characteristics different from those in the underdoped regime: (i) the absence of muon-spin precession as shown in Fig. 1, (ii) the sharp magnetic transition as shown in Fig.…”

“…With increasing field, the SC transition curve in ρ ab vs. T exhibits broadening characteristic of the underdoped high-T c cuprates. [12] The R H is almost independent of temperature above T d2 , whereas it suddenly decreases below T d2 . Moreover, a sign change of R H is observed below ∼ 26 K and eventually R H goes to zero at low temperatures.…”

“…The detailed procedures are described elsewhere. [4,12] The composition of each crystal was analyzed by the inductively coupledplasma (ICP) analysis. For LBCO and LNSCO with x = 0.10 − 0.12, the charge stripe order is formed at low temperatures below T d2 , [7,13,14] while it is not for LBCO with x = 0.08.…”

Temperature dependence of the Hall coefficient, RH, has been investigated in charge-spin stripe-ordered La-214 high-Tc superconductors. Using the simplest stripe-ordered system of La2−xBaxCuO4, it has been clarified that both the behavior of RH and its sign exhibit significant dependences on the hole concentration. That is, RH is zero in the ground state of the charge-spin stripe order at x = 1/8, while it is negative in the less-stabilized state of the charge stripe for x < 1/8. These are interpreted as owing to the delicate balance of the contributions of the hole-like Fermi surface and the possible electron pocket arising from the formation of the charge-spin stripe order.The Hall coefficient, R H , in the high-T c superconducting (SC) cuprates has attracted considerable attention owing to its peculiar behavior since the early stages of high-T c research. The R H in the normal state is strongly dependent on temperature, which is unusual in conventional metallic superconductors. The temperature dependence of R H at high temperatures has been explained based upon the Fermi-liquid model [1] or the two-carrier model [2] taking into account spin fluctuations or charge fluctuations, respectively, but the behavior at low temperatures has not yet been understood.The experimental results of R H at low temperatures in the La-214 cuprates such as La 2−x Ba x CuO 4 (LBCO) [3][4][5] and La 1.6−x Nd 0.4 Sr x CuO 4 (LNSCO) [6] at x ∼ 1/8 have revealed that R H markedly decreases with decreasing temperature below the structural-phase-transition temperature between the tetragonal low-temperature (TLT) phase (space group: P 4 2 /ncm) and the orthorhombic mid-temperature (OMT) phase (Bmab), T d2 . This has been explained as owing to the disappearance of the Hall voltage in the one-dimensional (1D) charge stripe-ordered state [7] stabilized through the structural phase transition [6] Recently, measurements of R H in high magnetic fields for underdoped YBCO with the hole concentration per Cu in the CuO 2 plane, p = 0.10 − 0.14 by LeBoeuf et al. [11] have revealed a sign change of R H at low temperatures. They have proposed that the negative R H originates from the formation of an electron pocket through the reconstruction of the Fermi surface caused by the possible formation of the charge stripe order. In YBCO, however, effects of the possible charge stripe order on various physical properties are relatively weak compared with those in the La-214 cuprates, preventing one from understanding explicitly the relation between the electron pocket and the charge stripe order.In this Rapid Communication, R H in the charge stripeordered state is investigated in La-214 cuprates with various values of p. It has been found in LBCO with x = 0.08 − 0.12 and LNSCO with x = 0.12 that the behavior of R H including the sign at low temperatures exhibits a significant dependence on p. That is, R H for x = 0.10 − 0.12 undergoing the phase transition to the TLT phase markedly decreases with decreasing temperature below T d2 . Moreover, a sign change ...
