A series of experimental studies established that the differing morphologies of the phase
diagrams versus hole do** nh of the various cuprate families are mostly controlled by …

The shape of 3 d-orbitals often governs the electronic and magnetic properties of correlated
transition metal oxides. In the superconducting cuprates, the planar confinement of the dx 2 …

Abstract Current-voltage (I− V) characteristics were used to investigate the response of the
vortex-glass (VG) phase transition in high-quality epitaxial YBa 2 Cu 3 O 7− δ films in …

The value of the isotope coefficient could be greatly affected by a number of factors not
related to the lattice dynamics. Among them are magnetic scattering, the presence of a …

In-plane (ρ ab) and out-of-plane (ρ c) resistivities of Y 1− x Pr x Ba 2 Cu 3 O 7− δ have been
determined using the electrical contact configuration of the dc flux transformer. ρ c (x) varies …

A model Hamiltonian, which includes the components of the CuO 2 planes, CuO 3 chains,
and the Pr-O hybridization, is considered to describe the electronic structure of Y 1− x Pr x …

We show that various factors can lead to an isotopic dependence of the penetration depth δ.
Nonadiabaticity (Jahn-Teller crossing) leads to the isotope effect of the charge-carrier …

The vortex-solid phase boundary of YBa 2 Cu 3 O 7− δ (YBCO) thin films was studied as a
function of oxygen stoichiometry, δ, using magnetotransport measurements. Experimental …

The maximum value Δ of the negative Hall resistivity ρ xy of Y 1− x Pr x Ba 2 Cu 3 O 7− δ
(0≤ x≲ 0.13) and YBa 2 Cu 3 O y (6.73≲ y≤ 6.84) single crystals scales with T/T c …
