| Abstract: | Growth of large single crystals of quasi-two-dimensional Ln2NiO4 (Ln = La, Pr, Nd) has been accomplished using the radio frequency technique of skull melting under controlled oxygen partial pressures. No evidence of intergrowth of other phases such as Ln3Ni2O7 or higher homologs was observed. Determination of the Ni3+ content indicates that the crystals are cation deficient. |
