Correlated Spin Canting in Ordered Core-Shell Fe 3 O 4 /Mn x Fe 3-x Od4^ Nanoparticle Assemblies

March 18, 2019
Author(s)
Y. Ijiri, Kathryn L. Krycka, I. Hunt-Isaak, H. Pan, J. Hsieh, Julie Borchers, James Jennings Rhyne, Samuel D. Oberdick, A. Abdelgawad, S. A. Majetich
Polarization-analyzed small-angle neutron scattering methods are used to determine the spin arrangements in ordered three-dimensional assemblies of 7.4 nm diameter core-shell Fe 3O 4/Mn xFe 3-xO 4 nanoparticles. In moderate to high magnetic fields, the

Spin Waves Across Three-Dimensional, Close-Packed Nanoparticles

December 21, 2018

Kathryn Krycka, James Jennings Rhyne, Samuel D Oberdick, Ahmed M. Abdelgawad, Julie A. Borchers, Yumi Ijiri, Sara A. Majetich, Jeffrey W. Lynn
Inelastic neutron scattering is utilized to measure the spin waves, or magnons, which arise from inter-particle coupling between 8.4 nm ferrite nanoparticles that are self-assembled into a close-packed lattice, yet physically separated by oleic acid
