This article constructs time-dependent asymptotic solutions to the magnetic Schrödinger equation in the weak magnetic field limit in the case of “interband magnetic breakdown”. This means that there is an eigenvalue crossing in the (Bloch) spectrum of the zero magnetic field operator and interband tunnelling effects occur.
