Abstract

¹³⁹La NQR study has been performed on La₂NiO_4+δ and La₂CoO_4−δ. Experimental spectra at low temperatures provided an evidence for the existence of antiferromagnetic ordering in both of them. The internal field at La site in La₂NiO_4+δ (19.3 kOe, ∥ c-axis) and in La₂CoO_4−δ (30.5 kOe, ∥ c-axis) was significantly large comparing with that in La₂CuO_4−δ (1.0 kOe 1 ⊥ c-axis), suggesting an importance of exchange interactions via apex oxygen atoms.
