Pseudogap in underdoped cuprate seen in longitudinal magnetoresistance
by Artur Malinowski, Valeriy L Bezusyy, Piotr Nowicki
We report the results of in-plane magnetotransport study of slightly underdoped cuprate La_1.85Sr_0.15CuO₄ (LSCO15) with Ni impurity. Increasing Ni content y causes a sharp drop in longitudinal magnetoresistance (LMR) in LSCO15 to broaden and move towards higher temperatures. Temperature T m L M R ( y ) of this local maximum in LMR coincides with temperature T d e v ( y ) , below which ideal resistivity from the parallel-resistor model deviates from its T ²-dependence. A direct comparison with the hole doping evolution of pseudogap (PG) in La 2 − x Sr_xCuO₄ (LSCO), possible through the mobile-carrier concentration extracted from the thermopower measurements, allows to equate both characteristic temperatures T m L M R ≅ T d e v with PG opening temperature T ∗ . The rate of PG closing by magnetic field parallel to the CuO₂ plane, in measurements up to 9 T, is consistent with spin-paramagnetic effect in this configuration and yields PG closing field B _pc close to the second critical field B c 2 predicted for superconducting gap with the help of Werthamer–Helfand–Hohenberg theory. The field anisotropy of B _pc suggests that orbital degrees of freedom also play a role in PG formation.

Saturation of resistivity and Kohler's rule in Ni-doped ${La}_{1.85} {Sr}_{0.15} {CuO}_{4}$ cuprate
by A. Malinowski, V. L. Bezusyy, P. Nowicki
We present the results of electrical transport measurements of ${La}_{1.85} {Sr}_{0.15} {Cu}_{1 - y} {Ni}_{y} O_{4}$ thin single-crystal films at magnetic fields up to 9 T. Adding Ni impurity with strong Coulomb scattering potential to a slightly underdoped cuprate makes the signs of resistivity saturation at $ρ_{sat}$ visible in the measurement temperature window up to 350 K. Employing the parallel-resistor formalism reveals that $ρ_{sat}$ is consistent with the classical Ioffe-Regel-Mott limit and changes with carrier concentration $n$ as $ρ_{sat} \propto 1 / \sqrt{n}$ . Thermopower measurements show that Ni tends to localize mobile carriers, decreasing their effective concentration as $n ≅ 0.15 - y$ . The classical unmodified Kohler's rule is fulfilled for magnetoresistance in the nonsuperconducting part of the phase diagram when applied to the ideal branch in the parallel-resistor model.

Transition-metal substitutions in iron chalcogenides
by V. L. Bezusyy, D. J. Gawryluk, A. Malinowski, Marta Z. Cieplak
The $a b$ -plane resistivity and Hall effect are studied in ${Fe}_{1 - y} M_{y} {Te}_{0.65} {Se}_{0.35}$ single crystals doped with two transition-metal elements, M = Co or Ni, over a wide doping range, $0 \leq y \leq 0.2$ . The superconducting transition temperature, $T_{c}$ , reaches zero for Co at $y ≃ 0.14$ and for Ni at $y ≃ 0.032$ , while the resistivity at the $T_{c}$ onset increases weakly with Co doping, and strongly with Ni doping. The Hall coefficient $R_{H}$ , positive for $y = 0$ , remains so at high temperatures for all $y$ , while it changes sign to negative at low $T$ for $y > 0.135$ (Co) and $y > 0.06$ (Ni). The analysis based on a two-band model suggests that at high $T$ residual hole pockets survive the doping, but holes get localized upon the lowering of $T$ , so that the effect of the electron doping on the transport becomes evident. The suppression of the $T_{c}$ by Co impurity is related to electron doping, while in the case of the Ni impurity strong electron localization most likely contributes to fast decrease of the $T_{c}$ .

Spin-glass behavior in Ni-doped La $_{1.85}$ Sr $_{0.15}$ CuO $_{4}$
by A. Malinowski, V. L. Bezusyy, R. Minikayev, P. Dziawa, Y. Syryanyy, M. Sawicki
The dynamic and static magnetic properties of La1.85Sr0.15Cu1-yNiyO4 with Ni concentration up to y=0.63 are reported. All the features that characterize the spin-glass (SG) behavior are found: bifurcation of the dc susceptibility $\chi${} versus temperature curve, a peak in the zero-field-cooling branch of this curve accompanied by a step in the imaginary part of the ac susceptibility $\chi${}ac, frequency dependence of the peak position in the real part of $\chi${}ac, and scaling behavior. The decay of remanent magnetization is described by a stretched-exponential function. The characteristic time from the critical slowing-down formula that governs the dynamics of the system suggests the existence of the spin clusters. The strongest interactions between the fluctuating entities are at y equal to the charge-carrier concentration in the system. The SG transition temperature decreases linearly with decreasing y for y$\leqslant${}0.30 and extrapolates to 0 K at y=0, which means that Ni displays a magnetic character in the surrounding Cu-O network starting from the smallest concentration y. The static critical exponents characterizing the scaling behavior of the nonlinear part of $\chi${} lie between those typical for three-dimensional Ising-like and Heisenberg-like systems.
