摘要：
Low temperature magnetic structure of Sr substituted NdCrO3 has been investigated using neutron diffraction in the temperature range of 2-300 K. We carried out a low temperature magnetization study in the temperature range 5-300 K. The Rietveld analysis of neutron diffraction patterns led us to conclude that the Cr moments have a G(y) type of alignment of spins while the Nd moments align in a -C-z type fashion for all three samples. The weighted average Cr3+/4+ ions moments were 3.19(7), 2.77(3) and 2.57(7) mu(B) close to its theoretical Cr3+ moment value namely 3 mu(B) at 2 K for the x=0.05, 0.1 and 0.15 samples respectively. While the Nd3+ moments for the three samples at 2 K were 3.0(1), 2.39(8) and 2.2(2), respectively. (C) 2014 Elsevier B.V. All rights reserved.
