Abstract

A series of La_3-xTb_xNi₂O_7-δ samples have been synthesized for the first time, and the effects of Tb doping in La₃Ni₂O_7-δ are investigated through a comprehensive investigation on the structural parameters, electrical transport, and magnetic properties of the La_3-xTb_xNi₂O_7-δ samples. Novel magnetic ordered state has been observed both in the as-prepared La_3-xTb_xNi₂O_7-δ compounds and in the samples after high oxygen pressure annealing. The high oxygen pressure annealing results in substantial enhancement of the oxygen content and the increase of nominal valence state of Ni in the La_3-xTb_xNi₂O_7-δ samples, leading to an enhanced conductivity. The present work could contribute to the exploration of possible ambient pressure superconductivity in doped La₃Ni₂O_7-δ systems.
