摘要	Magnetic properties of spin-ladder compounds Sr(14)(Cu(1-y)Fe(y))(24)O(41) (0 <= y <= 0.05) are investigated in the temperature range from 10 to 300 K. The result reveals that all the samples exhibit magnetic crossover behavior in the paramagnetic range, and Fe(3+) doping can efficiently increase the susceptibility due to the large moment of Fe(3+). Both the observations are consistent with our previous investigation on transport behaviors, indicating the strong correlation between the magnetism and transport behaviors. The spin gap is evidenced in all the samples, and strengthens as Fe(3+) doping level increases, which can be associated with the antiferromagnetic interaction between Fe(3+) and Cu cations.
