Magnetic Structures and Spin-wave Excitations in Rare-Earth Iron Garnets near the Compensation Temperature
Michiyasu Mori, Timothy Ziman
We introduce a simple model for the ferrimagnetic non-collinear ``magnetic umbrella" states of rare-earth iron garnets (REIG), common when the rare-earth moments have non-zero orbi…
Origin and dynamics of umbrella states in rare-earth iron garnets
Bruno Tomasello, Dan Mannix, Stephan Geprägs +1
Rare-earth iron garnets FeO are fascinating insulators with very diverse magnetic phases. Their strong potential in spintronic devices has encouraged a renewal…
Ground state selection by magnon interactions in the fcc antiferromagnet
R. Schick, O. Götze, T. Ziman +3
We study the nearest-neighbor Heisenberg antiferromagnet on a face-centered cubic lattice with arbitrary spin S. The model exhibits degenerate classical ground states including two…
Noncoplanar multi-k states in frustrated spinel and kagome magnets
M. E. Zhitomirsky, M. V. Gvozdikova, T. Ziman
We investigate analytically and numerically the classical ground states of frustrated Heisenberg models on pyrochlore and kagome lattices in zero and finite magnetic fields. Each m…
Controlling magnetic configuration in soft-hard bilayers probed by polarized neutron reflectometry
Nan Tang, Jung-Wei Liao, Siu-Tat Chui +4
Hard/soft magnetic bilayer thin films have been widely used in data storage technologies and permanent magnet applications. The magnetic configuration and response to temperatures…
Superconducting spin valves based on a single spiral magnetic layer
N. G. Pugach, M. O. Safonchik, V. I. Belotelov +2
A detailed investigation of a superconducting spin-triplet valve is presented. This spin-valve consists of a superconducting film covering a metal with an intrinsic spiral magnetic…
