Abstract

In order to investigate The possible ferromagnetic phase in The non-superconducting (non-SC) heavily overdoped (HOD) regime of high-Tc cuprates suggested by Sonier et al. [Proc. Natl. Acad. Sci. USA 107, 17131 (2010)] in La2-xSrxCuO4, both The magnetization and in-plane electrical resistivity, ρab, have been measured using single crystals of Bi1.76Pb0.35Sr1.89CuO6+δ covering a wide range of hole concentration. Magnetization curves in The non-SC HOD regime have shown a tendency to be saturated in high magnetic fields at low temperatures, which is probably a precursor of The possible ferromagnetic transition at a lower temperature. In addition, it has been found that ρab exhibits The temperature dependence being proportional to T4.3, which is characteristic of a metal with two-dimensional ferromagnetic fluctuations, in a wide range of hole concentration from The superconducting overdoped to The non-SC HOD regime. It has been concluded that two-dimensional ferromagnetic correlation develops at low temperatures in HOD Bi-2201 and that therefore The development of The ferromagnetic correlation is probably an intrinsic feature in The HOD cuprates.
