Phase separation in oxygen deficient ΗοBa2Cu3O7-δ single crystals: effect of high pressure and twin boundaries
We investigate the influence of high hydrostatic pressure on the electrical resistance in the ab-plane in HoBa2Cu3O7– δ single crystals with oxygen deficiency. It is determined that theExpand

Oxygen transport in perovskite and related oxides: A brief review
Abstract Perovskites and related oxides are a very important class of functional materials that exhibit a range of stoichiometries and crystal structures. The oxygen diffusion mechanisms andExpand

Effect of high pressure on the fluctuation conductivity and the charge transfer of YBa2Cu3O7−δ single crystals
Abstract The influence of hydrostatic pressure of up to 11 kbar on the fluctuation conductivity in the ab plane of the YBa 2 Cu 3 O 7−δ (YBCO) single crystals with various oxygen concentrations isExpand

Effect of small oxygen deficiency on the para-coherent transition and 2D–3D crossover in untwinned YBa2СuзО7−δ single crystals
Abstract We investigate the influence of the disorientation angle between the direction of a constant magnetic field (up to 15 kOe) and the ab-plane α  ≡ ∠( H ,ab) to the temperature dependence ofExpand

Effect of long aging on the resistivity properties of optimally doped YBa2Cu3O7−δ single crystals
Abstract We investigate the conducting properties in the basal ab-plane before and after a long time exposure in air atmosphere of the optimally oxygen doped YBa 2 Cu 3 O 7− δ single crystals.Expand

Resistive investigation of pseudogap state in non-stoichiometric ReBa2Cu3O7−δ (Re = Y, Ho) single crystals with account for BCS–BEC crossover
Abstract We investigate the conductivity in the basis plane of the non-stoichiometric ReBa2Cu3O7−δ (Re = Y, Ho) single crystals. The excess conductivity (Δσ) is described by Δ σ ∼ ( 1 − T / T * ) expExpand

Structural relaxation, metal-to-insulator transition and pseudo-gap in oxygen deficient НоBa2Cu3O7−δ single crystals
Abstract The effect of annealing at room temperatures on the conductivity in the basis plane of oxygen deficient HoВа 2 Сu 3 О 7− δ single crystals, tempered from a temperature of 650 °C isExpand

Excess conductivity and pseudo-gap state in YBCO single crystals slightly doped with Al and Pr
In this work we investigate the conductivity in the base plane of YBa2Cu3O7 (YBCO) single crystals with slight (up to 5%) aluminium (Al) and praseodymium (Pr) doping and with a given topology ofExpand

Electro-transport and structure of 1-2-3 HTSC single crystals with different plane defects topologies
In this work we study the structural and resistivity parameters of the 1-2-3 system HTSC single crystals by substituting yttrium to holmium and with a low (5%) aluminum doping. It was determined thatExpand
