Y. Hanaki et al., Zn-doping effect on the magnetotransport properties of Bi2Sr2-xLaCuO6+delta single crystals - art. no. 172514, PHYS REV B, 6417(17), 2001, pp. 2514
We report the magnetotransport properties of Bi2Sr2-xLaCu1-zZnzO6+delta (Zn
-doped BSLCO) single crystals with z of up to 2.2%. Besides the typical Zn-
doping effects on the in-plane resistivity and the Hall angle, we demonstra
te that the nature of the low-temperature normal state in the Zn-doped samp
les is significantly altered from that in the pristine samples under high m
agnetic fields. In particular. we observe nearly-isotropic negative magneto
resistance as well as an increase in the Hall coefficient at very low tempe
ratures in nonsuperconducting Zn-doped samples, which we propose to be caus
ed by the Kondo scattering from the local moments induced by Zn impurities.
