摘要:
AbstractThe behaviour of the Fourier component of a longitudinal spin pair correlation function near the Curie point is considered on the base of results of [1, 2]. It is shown, that in the small wave vectors limit whenT→Tcthe results of [1] and [2]are equal. The formula obtained is substituted in the general expressions for the r.f. susceptibility and the width of the resonance lin
