Evolution of the commensurate and incommensurate magnetic phases of the S = 3/2 kagome staircase Co3V2O8 in an applied field
Joel S. Helton, Ying Chen, Georgii L. Bychkov +4
Single crystal neutron diffraction studies have been performed on the S = 3/2 kagome staircase compound Co3V2O8 with a magnetic field applied along the magnetization easy-axis (H |…
Magnetic Order of the Hexagonal Rare Earth Manganite Dy(0.5)Y(0.5)MnO3
Joel S. Helton, Deepak K. Singh, Harikrishnan S. Nair +1
Hexagonal Dy(0.5)Y(0.5)MnO3, a multiferroic rare-earth manganite with geometrically frustrated antiferromagnetism, has been investigated with single-crystal neutron diffraction mea…
Synthesis and Characterization of Single Crystal Samples of Spin- Kagome Lattice Antiferromagnets in the Zn-Paratacamite Family ZnCu(OH)Cl
Tianheng Han, Joel S. Helton, Shaoyan Chu +6
The Zn-paratacamite family, ZnCu(OH)Cl for 0.33, is an ideal system for studying spin-1/2 frustrated magnetism in the form of antiferromagneti…
Numerical study of the thermodynamics of clinoatacamite
Ehsan Khatami, Joel S. Helton, Marcos Rigol
We study the thermodynamic properties of the clinoatacamite compound, Cu_2(OH)_3Cl, by considering several approximate models. They include the Heisenberg model on (i) the uniform…
Dzyaloshinskii-Moriya interaction and spin re-orientation transition in the frustrated kagome lattice antiferromagnet
K. Matan, B. M. Bartlett, J. S. Helton +10
Magnetization, specific heat, and neutron scattering measurements were performed to study a magnetic transition in jarosite, a spin-5/2 kagome lattice antiferromagnet. When a magne…
