Ferroelectrically induced weak-ferromagnetism in a single-phase multiferroic by design
Craig J. Fennie
We present a strategy to design structures for which a polar lattice distortion induces weak ferromagnetism. We identify a large class of multiferroic oxides as potential realizati…
Spin-Filtering Multiferroic-Semiconductor Heterojunctions
Na Sai, Jaekwang Lee, Craig J. Fennie +1
We report on the structural and electronic properties of the interface between the multiferoic oxide YMnO and wide band-gap semiconductor GaN studied with the Hubbard-corrected…
Viscous spin exchange torque on precessional magnetization in superlattices
H. B. Zhao, K. J. Smith, Y. Fan +6
Photoinduced magnetization dynamics is investigated in chemically ordered superlattices using the time-resolved magneto-optic Kerr ef…
Demagnetization Protocols for Frustrated Interacting Nanomagnet Arrays
R. F. Wang, J. Li, W. McConville +8
We report a study of demagnetization protocols for frustrated arrays of interacting single domain permalloy nanomagnets by rotating the arrays in a changing magnetic field. The mos…
