Doping and temperature dependence of electron spectrum and quasiparticle dispersion in doped bilayer cuprates
Yu Lan, Jihong Qin, Shiping Feng
Within the t-t'-J model, the electron spectrum and quasiparticle dispersion in doped bilayer cuprates in the normal state are discussed by considering the bilayer interaction. It i…
Pressure dependence of superconductivity in doped two-leg ladder cuprates
Jihong Qin, Ting Chen, Shiping Feng
Within the kinetic energy driven superconducting mechanism, the effect of the pressure on superconductivity in doped two-leg ladder cuprates is studied. It is shown that the superc…
Comparison of room-temperature multiferroics in Bi4Fe2TiO12 film and bulk
J. Lu, L. J. Qiao, W. Y. Chu
It is reported that both dielectricity and magnetism at room temperature have been appreciably improved in Bi4Fe2TiO12 film compared with that of Bi4Fe2TiO12 bulk. X-ray diffractio…
Superconductivity in doped two-leg ladder cuprates
Jihong Qin, Feng Yuan, Shiping Feng
Within the t-J ladder model, superconductivity with a modified d-wave symmetry in doped two-leg ladder cuprates is investigated based on the kinetic energy driven superconducting m…
Magnetodielectric effect of Bi6Fe2Ti3O18 film under an ultra-low magnetic field
J. Lu, L. J. Qiao, X. Q. Ma +1
Good quality and fine grain Bi6Fe2Ti3O18 magnetic ferroelectric films with single-phase layered perovskite structure have been successfully prepared via metal organic decomposition…
