Effect of Oxygen Partial Pressure on the Nucleation Kinetics of Orthorhombic YBCO

Effect of oxygen partial pressure on the nucleation kinetics of orthorhombic YBCO from tetragonal phase has been studied using classical nucleation theory. The free energy of formation of orthorhombic YBCO has been evaluated as a function of oxygen partial pressure.

Keywords: YBCO, oxygen partial pressure, phase transformation, nucleation kinetics
