Metastability-induced charge and spin fluctuations in 123 type superconductors
Various defects arising from lattice mismatch and coordination incompatibility at the cation sites are known to lend the cuprates a metastable state at temperatures and pressures where they exhibit superconduc...

Ag-do**-induced coordination incompatibility and its effect on superconductivity in YBCO
A series of samples of YBa2Cu3-xAgxO7-y with 0≤x≤0.12 composition was studied to probe into the Ag substitution effect on oxygen stoichiometry, lattice parameters, and superconducting properties. With the samples...

Effect of cobalt implantation on structural and optical properties of rutile TiO2(110)
Photo-absorption properties of Co implantation in rutile TiO2(110) have been investigated. Nearly five times enhancement in absorbance of visible light and 1.7 times increase in UV light have been observed. Forma...
