Abstract
General analytical expressions for the magnetization power spectral densities of particulate media are derived by using the three-dimensional autocorrelation function. Expressions include the effects of AC demagnetized media and any DC components resulting from the presence of particle chains. The replay flux power spectral density is then obtained, assuming a linear replay transducer
