Title: Magnetic ordering in TbMn{sub 0.5}Cr{sub 0.5}O{sub 3} studied by neutron diffraction and first-principles calculations

Abstract

The structure and magnetic ordering of bulk TbMn{sub 0.5}Cr{sub 0.5}O{sub 3} was revealed through bulk magnetization and neutron diffraction measurements, and first-principles calculations, respectively. G-type antiferromagnetic ordering of Mn{sup 3+} and Cr{sup 3+} moments was observed in the neutron diffraction data below Néel temperature T{sub N} ∼ 84 K. In addition, below ∼40 K, short-range magnetic ordering was identified correlating to a ferromagnetic component due to the canting of the moments along the c-axis. The spin configuration is consistent with the first-principles calculations. The magnetic structure revealed in the present TbMn{sub 0.5}Cr{sub 0.5}O{sub 3} sample is distinct from that observed for both end members TbMnO{sub 3} and TbCrO{sub 3}.

  • The structural and magnetic properties of the perovskite type compound LaFe{sub 0.5}Cr{sub 0.5}O{sub 3} have been studied by temperature dependent neutron powder diffraction and magnetization measurements. Rietveld refinement of the neutron diffraction data shows that the compound crystallizes in an orthorhombic perovskite structure with a random positioning of the Fe and Cr cations at the B sublattice. The magnetic structure at 10 K is a collinear antiferromagnetic one with the magnetic moment per site being equal to 2.79(4) {mu}{sub B}. Magnetisation measurements confirm the overall antiferromagnetic behaviour. Moreover, it indicates a weak uncompensated magnetic moment close to the transition temperaturemore » T {sub N} {approx} 265 K. This moment can be described by a magnetic cluster state, which remains up to 550 K. Electron diffraction patterns along with high-resolution transmission electron microscopy images reveal that the crystallites are composed by domains of different orientation, which share the same cubic perovskite sub-cell reflections.« less
  • This paper reports investigations into the influence of hydrogen on the magnetic properties of the YCo{sub 3}-H system. We report results on the magnetic structure and magnetic transitions of YCo{sub 3} using a combination of neutron powder diffraction measurements and first-principles full potential augmented plane wave + local orbital calculations under the generalized gradient approximation. The ferromagnetic and ferrimagnetic structures are examined on an equal footing. However, we identify that, no matter which structure is used as the starting point, the neutron diffraction data always refines down to the ferrimagnetic structure with the Co{sub 2} atoms having antiparallel spins. Inmore » the ab initio calculations, the inclusion of spin-orbit coupling is found to be important in the prediction of the correct magnetic ground state. Here, the results suggest that, for zero external field and sufficiently low temperatures, the spin arrangement of YCo{sub 3} is ferrimagnetic rather than ferromagnetic as previously believed. The fixed spin moment calculation technique has been employed to understand the two successive field-induced magnetic transitions observed in previous magnetization measurements under increasing ultrahigh magnetic fields. We find that the magnetic transitions start from the ferrimagnetic phase (0.61{mu}{sub B}/Co) and terminate with the ferromagnetic phase (1.16{mu}{sub B}/Co), while the spin on the Co{sub 2} atoms progressively changes from antiparallel ferrimagnetic to paramagnetic and then to ferromagnetic. Our neutron diffraction measurements, ab initio calculations, and the high field magnetization measurements are thus entirely self-consistent.« less
  • We report on the preparation and characterization of the Ca(Cr{sub 0.5}Mo{sub 0.5})O{sub 3} perovskite, obtained in the search of the hypothetical double perovskite Ca{sub 2}CrMoO{sub 6}. This material was prepared in polycrystalline form by solid state reaction in H{sub 2}/Ar flow. It has been studied by X-ray and neutron powder diffraction (NPD) and magnetic measurements. Ca(Cr{sub 0.5}Mo{sub 0.5})O{sub 3} crystallizes in the orthorhombic Pbnm (No. 62) space group, with the unit-cell parameters a=5.4110 (4) A, b=5.4795 (5) A, c=7.6938 (6) A. There is a complete disordering of Cr{sup 3+} and Mo{sup 5+} over the B-site of the perovskite, and themore » (Cr,Mo)O{sub 6} octahedra are tilted by 12.4{sup o} in order to optimize the Ca-O bond lengths. The magnetic susceptibility is characteristic of a ferrimagnetic behavior, with T {sub C}=125 K, and a small saturation magnetization at T=5 K, of 0.05 {mu} {sub B}/f.u. - Graphical abstract: Ca(Cr{sub 0.5}Mo{sub 0.5})O{sub 3} is orthorhombic, Pbnm space group, and exhibits a complete disordering of Cr{sup 3+} and Mo{sup 5+} over the B-site of the perovskite.

  • First-principles calculations based on density-functional theory in the pseudopotential approach have been performed for the energetics and crystal structure of Y{sub 2}Si{sub 3}O{sub 3}N{sub 4} with the melilite-type structure. The calculations show the following ordering of the O/N atoms in the crystal: N atoms fully occupy the bridging site (2c) and O atoms fully occupy the terminal site (4e) WITH 2 O and 6 N atoms at the bridging 8f site. These conclusions are in good agreement with the experimental results obtained with neutron diffraction. In addition, the calculations show that there is a preferential distribution of the O andmore » N atoms at the 8f site, resulting in two different local coordinations of Y, as compared to only a single averaged crystallographic Y site. All the nitrogen ions exhibit similar electronic structure, in contrast to the oxygen ions. However, there are slightly more electrons (about 0.1 electrons per ion) for nitrogen at the 2c site than those at the 8f site, while the silicon atoms have almost the same charge distribution.« less
