The stochastic Bloch equations driven by a coloured noise

In this Letter, the lagged cross-moments and cross-spectra of the Bloch equations driven by a radiofrequency field whose amplitude is fluctuating randomly with Markovian statistics are calculated. Exact expressions for the lineshape are derived in the special case of a Markovian binary noise. The limiting case of white noise is investigated and compared with results found in the literature.
