Nd1.33Na0.66Mn0.66Ti1.34O6 was synthesised in air and He atmospheres and wa
s characterised by X-ray diffraction by the Rietveld profile analysis. This
phase adopts a perovskite-type structure in which Nd and Na are randomly d
istributed on the A-sites and the Mn and Ti are on the B ones (space group
Pbnm). The electrical properties show a semiconductor behaviour with low ac
tivation energy. Magnetic susceptibility variation with temperature shows a
ntiferromagnetic interactions at 6 K. (C) 2001 Elsevier Science B.V. All ri
