Joel Helton, Deepak Singh, Harikrishnan S. Nair, Suja Elizabeth
Hexagonal Dy 0.5Y 0.5MnO 3, a multiferroic rare earth manganite with geometrically frustrated antiferromagnetism, has been investigated with neutron diffraction measurements. Below 2.4 K magnetic order is observed on both the Mn (antiferromagnetic) and Dy

Dzyaloshinskii-Moriya Interaction and Spin Re-Orientation Transition in the Frustrated Kagome Lattice Antiferromagnet

K. Matan, B. M. Bartlett, Joel Helton, V. Sikolenko, S. Mat'as, K. Prokes, Ying Chen, Jeffrey W. Lynn, D. Grohol, T. J. Sato, M. Tokunaga, D. G. Nocera, Y. S. Lee
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 magnetic field is applied perpendicular to the kagome plane, magnetizations in
