Abstract

The evolution behavior of a spin system subject to a time-varying magnetic field and the relevant two-level problem essentially exhibit like a rotation in a three-dimensional space. It is shown that the parametrization of this rotation is shifted into solving the time-dependent Schrödinger equation of a spin-1/2 system and the rotation parameters can thus be obtained by a straightforward method.
