Within the conventional framework of standard linear response theory we have
derived exact results for the initial static susceptibilities of nonuniform
spin-1/2 Ising chains. The results obtained permit one to study regularly
alternating-bond and random-bond Ising chains. The influence of several types
of nonuniformity and disorder on the temperature dependence of the initial
longitudinal and transverse static susceptibilities is discussed.Comment: LaTeX, 7 figure
