Abstract

Annealing and quenching experiments in a thermogravimetric analysis apparatus are used to vary the oxygen content in La2Ni1‐yCuy04+δ, followed by magnetic susceptibility and x‐ray diffraction experiments. These studies show that for certain δ, transition to antiferromagnetism occurs with TN < 20 K. The effect of Cu doping (y = 0.01 and 0.05) on TN is negligible.
