Magnetic properties and spin glass like behavior of Li1-xNi1+xO2 (x approximate to 0.03)

High quality sample of Li1-xNi1+xO2(x approximate to 0.03) was synthesized. The de and ac magnetic susceptibilities and the field dependence of magnet ization were measured by SQUID magnetometer between 4.5 and 300 K. The resu lts were compared with those obtained previously for the samples of x appro ximate to 0.01 and 0.05. The magnetic properties were found to be strongly dependent upon the nonstoichiometry x. The spin glass-like behavior was det ected in the sample of x approximate to 0.03. The properties of the sample of x approximate to 0.03 were found to be intermediate between those of x a pproximate to 0.01 (typical spin glass) acid x approximate to 0.05 (mictoma gnet).
