Superconductivity in a unique type of copper oxide
W. M. Li, J. F. Zhao, L. P. Cao +18
The paper reports bulk superconductivity above 70 K in the cuprate Ba₂CuO₄₋y, which features unusually compressed CuO₆ octahedra that alter the orbital hierarchy and introduce thre…

Effects of Ni Substitutions on the Critical Behaviors in $Nd_{0.6}Sr_{0.4}Mn_{1-x}Ni_{x}O_{3}$ Manganite
M. Kh. Hamad, Y. Maswadeh, Kh. A. Ziq
The study examines how nickel substitution in the perovskite Nd₀.₆Sr₀.₄Mn₁₋ₓNiₓO₃ alters its crystal lattice and magnetic critical behavior, showing a transition from 3D Heisenberg…
