As an application of the general theory developed in the preceding paper, line width in the paramagnetic range of temperature is discussed in terms of the spatial correlations of spin deviations. It is shown that the width decreases monotonically with decreasing temperature and that it decreases more rapidly with decreasing temperature than that predicted by previous theories based on the second moment. This is considered as a consequence of the fact that the net effect of modulation due to the exchange interaction will be enhanced in the neighbourhood of the critical point. The effect of including the non-secular interaction is also examined. It is shown that the temperature dependence of width is not affected very much by them; however, its magnitude becomes 10/3 times that of the secular width in the limit of high temperature, which is consistent with the results obtained by other theories.
