Classical Spins in Superconductors

Key Points

• This research aims to analyze the presence of localized excited states in superconductors influenced by classical spins.
• Examined the formation of localized excited states in a superconductor with classical spin.
• Investigated the growth process of the impurity band created by these states.
• Assessing the impact of the impurity band on observable quantities in the superconductor.
• Localized excited states exist within the energy gap of superconductors with classical spins.
• An impurity band forms at finite concentrations around classical spins.
• The growth of the impurity band significantly affects observable physical properties.
