Title: Phase Diagram of a Three-Dimensional Antiferromagnet with Random Magnetic Anisotropy

Abstract

Three-dimensional (3D) antiferromagnets with random magnetic anisotropy (RMA) that were experimentally studied to date have competing two-dimensional and three-dimensional exchange interactions which can obscure the authentic effects of RMA. The magnetic phase diagram of Fe_xNi_1-xF₂ epitaxial thin films with true random single-ion anisotropy was deduced from magnetometry and neutron scattering measurements and analyzed using mean field theory. Regions with uniaxial, oblique and easy plane anisotropies were identified. A RMA-induced glass region was discovered where a Griffiths-like breakdown of long-range spin order occurs.

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

Magnetostriction of rare-earth random magnetic anisotropy spin glasses

Journal Article del Moral, A ; Arnaudas, J I - Phys. Rev. B: Condens. Matter; (United States)

A model of magnetostriction for single-ion random magnetic anisotropy (RMA) spin glasses (SG) is developed, the calculation being based on the replica technique. An overall uniform strain is assumed and coupled to the local easy axis (or easy plane) by an adequate projection. The obtained bulk magnetostriction becomes proportional to the average quadrupolar moment, which depends upon the assumed ferromagnetic uniform exchange, J/sub 0/, and the RMA crystal field (CEF), D/sub 0/, strengths. Magnetostriction measurements parallel (lambda/sub X/) and perpendicular (lambda/sub perpendicular/) to the applied magnetic field (up to 7 T) have been performed between 4.2 and 150 K (muchmore »« less

Phase-transition behavior in the random-field antiferromagnet Fe{sub 0.5}Zn{sub 0.5}F{sub 2}

Journal Article Hill, J P ; Feng, Q ; Harris, Q J ; ... - Physical Review, B: Condensed Matter

We present a combined magnetic x-ray and neutron scattering study of the order parameter of the diluted antiferromagnet Fe{sub 0.5}Zn{sub 0.5}F{sub 2} in an applied field. This system is believed to be modeled by the three-dimensional random-field Ising model. A long range ordered (LRO) state is prepared through a zero-field-cooled procedure (ZFC). The evolution of this LRO state is studied on warming at fixed field. The x-ray order parameter data are well described by a power-law-like transition at all fields with an exponent {beta}{sub ZFC} varying from 0.21 to 0.12. The transition region is broadened and may be described bymore »« less

Nature of the ferromagnetic-antiferromagnetic transition in Y_1-xLa_xTiO₃

Journal Article Hameed, S. ; El-Khatib, S. ; Olson, K. P. ; ... - Physical Review B

In this work, we explore the magnetically ordered ground state of the isovalently substituted Mott insulator Y_1-xLa_xTiO₃ for x≤ 0.3 via single-crystal growth, magnetometry, neutron diffraction, x-ray magnetic circular dichroism, muon spin rotation, and small-angle neutron scattering (SANS). We find that the decrease in the magnetic transition temperature on approaching the ferromagnetic-antiferromagnetic phase boundary at the La concentration xc ≈ 0.3 is accompanied by a strong suppression of both bulk and local ordered magnetic moments, along with a volume wise separation into magnetically ordered and paramagnetic regions. The thermal phase transition does not show conventional second-order behavior since neither amore »« less
