Manifolds of magnetic ordered states and excitations in the almost Heisenberg pyrochlore antiferromagnet MgCr2O4
S. Gao, K. Guratinder, V. Tsurkan +18
In spinels ACr2O4 (A=Mg, Zn) realisation of the classical pyrochlore Heisenberg antiferromagnet model is complicated by a strong spin-lattice coupling: the extensive degeneracy of…
Coupled multiferroic domain switching in the canted conical spin spiral system MnGeO
T. Honda, J. S. White, A. B. Harris +7
Despite remarkable progress in developing multifunctional materials, spin-driven ferroelectrics featuring both spontaneous magnetization and electric polarization are still rare. A…
Magnetic charge injection in spin ice: a new way to fragmentation
E. Lefrançois, V. Cathelin, E. Lhotel +10
The complexity embedded in condensed matter fertilizes the discovery of new states of matter, enriched by ingredients like frustration. Illustrating examples in magnetic systems ar…
Spin-stripe phase in a frustrated zigzag spin-1/2 chain
M. Pregelj, A. Zorko, O. Zaharko +4
Motifs of periodic modulations are encountered in a variety of natural systems, where at least two rival states are present. In strongly correlated electron systems such behaviour…
Anisotropy tuned magnetic order in pyrochlore iridates
E. Lefrançois, V. Simonet, R. Ballou +7
The magnetic behavior of polycrystalline samples of ErIrO and TbIrO pyrochlores is studied by magnetization measurements and neutron diffraction. Both compo…
Magnetic order in the frustrated Ising-like chain compound SrNiIrO
Emilie Lefrançois, Laurent C. Chapon, Virginie Simonet +6
We have studied the field and temperature dependence of the magnetization of single crystals of Sr3NiIrO6. These measurements evidence the presence of an easy axis of anisotropy an…
Neutron scattering and muon spin relaxation measurements of the non-centrosymmetric antiferromagnet CeCoGe3
M. Smidman, D. T. Adroja, A. D. Hillier +10
The magnetic states of the non-centrosymmetric, pressure induced superconductor CeCoGe3 have been studied with magnetic susceptibility, muon spin relaxation(muSR), single crystal n…
MnSb2O6: A polar magnet with a chiral crystal structure
R. D. Johnson, K. Cao, L. C. Chapon +7
Structural and magnetic chiralities are found to coexist in a small group of materials in which they produce intriguing phenomenologies such as the recently discovered skyrmion pha…
Low temperature magnetic structure of geometrically frustrated SrHo2O4
Olga Young, Laurent C. Chapon, Oleg A. Petrenko
SrHo2O4 is a geometrically frustrated compound because the Ho^3+ ions are arranged in a network of triangles and hexagons and coupled with antiferromagnetic exchange interactions.…
Coexistence of the long-range and short-range magnetic order components in SrErO
T. J. Hayes, G. Balakrishnan, P. P. Deen +3
Single crystal neutron diffraction reveals two distinct components to the magnetic ordering in geometrically frustrated SrErO. One component is a long-range ordered ${\bf k…
One-dimensional magnetic fluctuations in the spin-2 triangular lattice α-NaMnO2
C. Stock, L. C. Chapon, O. Adamopoulos +6
The S=2 anisotropic triangular lattice alpha-NaMnO2 is studied by neutron inelastic scattering. Antiferromagnetic order occurs at T ~ 45 K with opening of a spin gap. The spectral…
Field-induced avalanche to the ferromagnetic state in the phase-separated ground state of manganites
F. M. Woodward, J. W. Lynn, M. B. Stone +5
Perovskite manganite compounds such as Pr_(1-x)(Ca_(1-y)Sr_y)_xMn3 can be tuned to exhibit a metastable ground state where two magnetic/crystallographic phases coexist in zero magn…
