Gorter-Casimir two-fluid expression for the temperature dependence of the magnetic penetration depth.

Parameters:

• T – Absolute temperature (K).

• T_c – Superconducting transition temperature (K).

• lambda_0 – Magnetic penetration depth at 0 K (nm).

Returns:

The magnetic penetration depth at finite temperature.
