WebbThe theory that describes diamagnetism in a free electron gas is called Landau diamagnetism, named after Lev Landau, [19] and instead considers the weak counteracting field that forms when the electrons' trajectories are curved due to the Lorentz force. Webbwhere n+ n + is the electron density with μs μ s in field direction and n− n − the density with μs μ s against the field direction. Without the Pauli paramagnetism in the free electron model we get for thermal equilibrium, n++n− = n+∗ n− n+ =e− ΔE kBT n + + n − = n + ∗ n − n + = e − Δ E k B T. And for the occupation ...
