中文摘要	we report the heat, magnetic, and dielectric properties of la2-xbixcomno6 with a series of bi doping concentrations, focusing especially on the impact of a-site doping on b-site ordering. we demonstrate that the b-site ordering is enhanced via the bi doping, resulting in a suppressed cluster-glass behavior, larger dielectric constant, and smaller tangent loss. surprisingly, a pronounced step-like dielectric anomaly turns up near the spin-freezing temperature in the bi-free oxide, which is suppressed significantly after bi doping. we attribute the suppression of anomaly to the lessened amount of antisite defects at the b sites and the associated strengthened electronic localization.
