Title: Crystal structure and partial Ising-like magnetic ordering of orthorhombic $D y_{2} Ti O_{5}$

Abstract

The structure and magnetic properties of orthorhombic Dy₂TiO₅ have been investigated using x-ray diffraction, neutron diffraction, and alternating current (ac)/direct current (dc) magnetic susceptibility measurements. In this paper, we report a continuous structural distortion below 100 K characterized by negative thermal expansion in the [0 1 0] direction. Neutron diffraction and magnetic susceptibility measurements revealed that two-dimensional (2D) magnetic ordering begins at 3.1 K, which is followed by a three-dimensional magnetic transition at 1.7 K. The magnetic structure has been solved through a representational analysis approach and can be indexed with the propagation vector k = [0 1/2 0]. The spin structure corresponds to a coplanar model of interwoven 2D “sheets” extending in the [0 1 0] direction. The local crystal field is different for each Dy³⁺ ion (Dy1 and Dy2), one of which possesses strong uniaxial symmetry indicative of Ising-like magnetic ordering. In conclusion, consequently, two succeeding transitions under magnetic field are observed in the ac susceptibility, which are associated with flipping each Dy³⁺ spin independently.

Fragile singlet ground-state magnetism in the pyrochlore osmates $R_{2} {Os}_{2} O_{7}$ ( $R = Y$ and Ho)

Journal Article Zhao, Z. Y. ; Calder, S. ; Aczel, A. A. ; ... - Physical Review B

The singlet ground state magnetism in pyrochlore osmates Y₂Os₂O₇ and Ho₂Os₂O₇ is studied by DC and AC susceptibility, specific heat, and neutron powder diffraction measurements. Despite the expected non-magnetic singlet in the strong spin-orbit coupling (SOC) limit for Os⁴⁺ (5d⁴), Y₂Os₂O₇ exhibits a spin-glass (SG) ground state below 4 K with weak magnetism, suggesting possible proximity to a quantum phase transition between the non-magnetic state in the strong SOC limit and the magnetic state in the strong superexchange limit. Ho₂Os₂O₇ has the same structural distortion as occurs in Y₂Os₂O₇. However, the Os sublattice in Ho₂Os₂O₇ shows long- range magnetic orderingmore »« less

Magnetic phase diagram and multiferroicity of ${Ba}_{3} {MnNb}_{2} O_{9}$ : A spin - $\frac{5}{2}$ triangular lattice antiferromagnet with weak easy-axis anisotropy

Journal Article Lee, M. ; Choi, E. S. ; Huang, X. ; ... - Physical Review. B, Condensed Matter and Materials Physics

Here we have performed magnetic, electric, thermal and neutron powder diffraction (NPD) experiments as well as density functional theory (DFT) calculations on Ba₃MnNb₂ O₉. All results suggest that Ba₃MnNb₂ O₉ is a spin-5/2 triangular lattice antiferromagnet (TLAF) with weak easy-axis anisotropy. At zero field, we observed a narrow two-step transition at T_N1 = 3.4 K and T_N2 = 3.0 K. The neutron diffraction measurement and the DFT calculation indicate a 120 spin structure in ab plane with out-of-plane canting at low temperatures. With increasing magnetic field, the 120 spin structure evolves into up-up-down (uud) and oblique phases showing successive magneticmore »« less

Magnetic structure of the mixed antiferromagnet ${NdMn}_{0.8} {Fe}_{0.2} O_{3}$

Journal Article Mihalik, Matus ; Mihalik, Marian ; Hoser, Andreas ; ... - Physical Review B

The magnetic structure of the mixed antiferromagnet NdMn_0.8Fe_0.2O₃ was resolved. Neutron powder diffraction data definitively resolve the Mn sublattice with a magnetic propagation vector k=(000) and with the magnetic structure (A_x, F_y, G_z) for 1.6 K _N(≈ 59 K). The Nd sublattice has a (0, f_y, 0) contribution in the same temperature interval. The Mn sublattice undergoes a spin-reorientation transition at T₁ ≈ 13 K while the Nd magnetic moment abruptly increases at this temperature. Powder x-ray diffraction shows a strong magnetoelastic effect at T_N but no additional structural phase transitions from 3 to 300 K. Density functional theory calculationsmore »« less

Complex magnetism and strong electronic correlations in ${Ce}_{2} {PdGe}_{3}$

Journal Article Baumbach, R. E. ; Gallagher, A. ; Besara, T. ; ... - Physical Review. B, Condensed Matter and Materials Physics

Single-crystal x-ray diffraction, magnetic susceptibility, magnetization, heat capacity, and electrical resistivity measurements are reported for the new tetragonal compound Ce₂PdGe₃, which forms in the space group P4₂/mmc (No. 131)—a relative of the α₋ThSi₂-type structure. Measurements reveal a two-part antiferromagnetic phase transition at T_N,1=10.7 K and T_N,2=9.6 K and subsequent ferromagnetlike ordering near TC≈2.25 K. The ordered ground state emerges from a lattice of Ce ions that are hybridized with the conduction electrons, as revealed by the enhanced electronic coefficient of the specific heat γ≈50 mJ/mol-Ce-K² (extrapolated to T=0 for T < T_C). Lastly, electronic structure calculations reveal a Fermi surfacemore »« less

Spin freezing into a disordered state in $CaFeT i_{2} O_{6}$ synthesized under high pressure

Journal Article Li, Xiang ; Xu, W. M. ; McGuire, Michael A. ; ... - Physical Review B

Double perovskites exhibit a variety of interesting phenomena due to numerous combinations of cation orderings and distortions. CaMnTi₂O₆ and CaFeTi₂O₆ are the only two discovered double perovskites that have the columnar type A-site ordering associated with the a⁺a⁺c^– titling system. The former perovskite, synthesized recently, has a polar structure below T_c and shows an unusual ferroelectricity. The latter, while synthesized decades ago, received less investigation. Here, we have synthesized CaFeTi₂O₆ under high pressure and carried out thorough characterizations through measurements of x-ray powder diffraction (XRD), second harmonic generation (SHG), dc and ac magnetization, Mössbauer spectra, resistivity, thermoelectric power, and specificmore »« less
