Fluctuational nonlocal diamagnetic response near the superconducting transition temperature
Barash Yu. S., Galaktionov A. V.
Expressions for the fluctuational component of the static value of the kernel Q{ k) are derived for a normal metal and for a superconductor near Tc. These components depend on the wave vector. Certain consequences of the nonlocal nature of the fluctuational diamagnetic response are discussed.
