Title: Origin of the net magnetic moment in ${LaCoO}_{3}$

Abstract

We use polarized neutron scattering to characterize the Bragg scattering intensity below T_C=89.5 K at the (1,0,0) pseudocubic nuclear Bragg point of LaCoO₃. Upon cooling in a field (FC), a net magnetic moment is apparent in Bragg scattering intensity, just as it was in previous magnetization measurements. Critical behavior associated with the net moment near T_C upon cooling in small applied fields rapidly rounds with increasing field strength. We show, using a mean-field calculation, that this net moment can develop in a metastable state that forms upon FC, even when all the interactions in the system are antiferromagnetic.

Manifolds of magnetic ordered states and excitations in the almost Heisenberg pyrochlore antiferromagnet ${MgCr}_{2} O_{4}$

Journal Article Gao, S. ; Guratinder, Kaur ; Stuhr, Uwe ; ... - Physical Review B

In spinels ACr₂O₄(A=Mg,Zn), realization of the classical pyrochlore Heisenberg antiferromagnet model is complicated by a strong spin-lattice coupling: the extensive degeneracy of the ground state is lifted by a magneto-structural transition at T_N=12.5 K. We study the resulting low-temperature low-symmetry crystal structure by synchrotron x-ray diffraction. The consistent features of x-ray low-temperature patterns are explained by the tetragonal model of Ehrenberg et al. [Pow. Diff. 17, 230 (2002)], while other features depend on sample or cooling protocol. A complex, partially ordered magnetic state is studied by neutron diffraction and spherical neutron polarimetry.

Strain-induced tetragonal distortions and multiferroic properties in polycrystalline ${Sr}_{1 - x} B a_{x} Mn O_{3}$ ( $x = 0.43 - 0.45$ ) perovskites

Journal Article Somaily, H. ; Kolesnik, S. ; Mais, J. ; ... - Physical Review Materials

Here, we report a comprehensive structure-property phase diagram of unique single-ion type-1 multiferroic pseudocubic Sr_1-xBa_xMnO₃ perovskites. Employing a specially designed multi-step reduction-oxidation synthesis technique, we describe the successful synthesis of previously unknown Sr_1-xBa_xMnO₃ compositions in their polycrystalline form with a significantly extended Ba solubility limit that is only rivaled by a very limited number of crystals and thin films grown under non-equilibrium conditions. Understanding the multiferroic interplay with structure in Sr_1-xBa_xMnO₃ is of great importance as it opens the door wide to the development of newer materials from the parent (AA’)(BB’) O₃ system with enhanced properties.

We have proposed the layered honeycomb magnet α - RuCl ₃ as a candidate to realize a Kitaev spin model with strongly frustrated, bond-dependent, anisotropic interactions between spin-orbit entangled j _eff= 1/2 Ru ^{3 +} magnetic moments. We report a detailed study of the three-dimensional crystal structure using x-ray diffraction on untwinned crystals combined with structural relaxation calculations. We consider several models for the stacking of honeycomb layers and find evidence for a parent crystal structure with a monoclinic unit cell corresponding to a stacking of layers with a unidirectional in-plane offset, with occasional in-plane sliding stacking faults, inmore »« less

Unconventional magnetic field response of the hyperhoneycomb Kitaev magnet $β - {Li}_{2} {IrO}_{3}$

Journal Article Li, Mengqun ; Rousochatzakis, Ioannis ; Perkins, Natalia B. - Physical Review Research

We present a unified description of the response of the hyperhoneycomb Kitaev magnet β–Li₂IrO₃ to applied magnetic fields along the orthorhombic directions a, b, and c. This description is based on the minimal nearest-neighbor J–K–Γ model and builds on the idea that the incommensurate counter-rotating order observed experimentally at zero field can be treated as a long-distance twisting of a nearby commensurate order with six spin sublattices. The results reveal that the behavior of the system for H∥a, H∥b, and H∥c share a number of qualitative features, including (i) a strong intertwining of the modulated, counter-rotating order with a set of uniform orders; (ii) the disappearance of the modulated order at a critical field H*, whose value is strongly anisotropic withmore »« less
