摘要：

<正> Longitudinal susceptibility of the spin-1/2 low-dimensional Heisenberg ferromagnet in a magnetic field,isstudied by the Green's function method within the random phase approximation.The static and dynamic longitudinalsusceptibilities are calculated in the low- and high-field regions.Power laws for the position and height of the staticsusceptibility maximum are shown not to support the predictions of Landau theory.
