remaining rare earth titanates, R ϭ Gd to Tm, ferri-and ferromagnetic behavior is observed (3).
The structural and magnetic properties of members belonging to the perovskite family, Nd 1؊x TiO 3 for x ؍ 0, 0.05, and
Interestingly, with such a rich variation in the magnetic 0.10, have been investigated. It is found that these compounds properties across the titanate series, evidence for magnetic adopt the GdFeO 3 -type structure belonging to the space group behavior and the determination of the magnetic structure Pnma. Magnetic susceptibility measurements indicate paraof neodymium titanate, NdTiO 3 , remained elusive. The magnetic Curie-Weiss behavior at temperatures typically magnetic properties of this compound were first investiabove 100 K. Antiferromagnetic ordering of the titanium sublatgated by Bazuev and Shveikin ( 7), who found it to be tice is observed at T N of 90 and 75 K for x ؍ 0 and 0.05, paramagnetic in the temperature range 77-450 K. Similar respectively. Investigation by low-temperature neutron diffracobservations were reported by Ganguly et al. (8) and Mation reveals evidence for magnetic ordering on both the titanium clean et al. (9). In addition, a low-temperature neutron and neodymium sublattices. The magnetic structure is found study by Greedan (6) seemed to provide the most concluto be consistent with that of PrTiO 3 and CeTiO 3 , having an sive evidence for paramagnetic behavior, since measure-F x C y configuration on the Nd 3؉ sublattice and a G z F x configuraments revealed no evidence of any magnetic ordering down tion for the moments on the Ti 3؉ sublattice. At 10 K, the refined to 7 K. Only recently, however, Eylem et al. (10) reported magnetic moments on the Nd 3؉ sublattice are determined to be 1.11(5) and 0.99(5) B and on the Ti 3؉ sublattice, 0.87(8) low field susceptibility and remanent moment measureand 0.74(9) B , for x ؍ 0 and 0.05, respectively. The antiferroments, which indicate that NdTiO 3 orders antiferromagmagnetic behavior vanishes at the x ؍ 0.10 composition.
