Effect of annealing on the specific heat of Ba(Fe1-xCox)2As2
Abstract
We report on the effect of annealing on the temperature and field dependencies of the low-temperature specific heat of the electron-doped Ba(Fe1-xCox)2As2 for under- (x = 0.045), optimally (x = 0.08), and over- (x = 0.105 and 0.14) doped regimes. We observed that annealing significantly improves some superconducting characteristics in Ba(Fe1-xCox)2As2. It considerably increases Tc, decreases γ0 in the superconducting state, and suppresses the …
