We report electrical-resistivity measurements and neutron-diffraction studies under magnetic fields of Bi{sub 1.75}Pb{sub 0.35}Sr{sub 1.90}Cu{sub 0.91}Fe{sub 0.09}O{sub 6+y}, in which hole carriers are overdoped. This compound shows short-range incommensurate magnetic correlation with incommensurability {delta} = 0.21, whereas a Fe-free compound shows no magnetic correlation. Resistivity shows an up turn at low temperature in the form of ln(1/T) and shows no superconductivity. We observe reduction in resistivity by applying magnetic fields (i.e., a negative magnetoresistive effect) at temperatures below the onset of short-range magnetic correlation. Application of magnetic fields also suppresses the Fe-induced incommensurate magnetic correlation. We compare and contrast these observations with two different models: (1) stripe order and (2) dilute magnetic moments in a metallic alloy with associated Kondo behavior. The latter picture appears to be more relevant to the present results.
