Low temperature neutron diffraction study of Nd1−xSrxCrO3 (0.05≤x≤0.15)

Abstract Low temperature magnetic structure of Sr substituted NdCrO 3 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 Cr 3+/4+ ions moments were 3.19(7), 2.77(3) and 2.57(7) µ B close to its theoretical Cr 3+ moment value namely 3 µ B at 2 K for the x =0.05, 0.1 and 0.15 samples respectively. While the Nd 3+ moments for the three samples at 2 K were 3.0(1), 2.39(8) and 2.2(2), respectively.
