TL;DR: In this article, the dynamics of labyrinth domain networks in ferromagnetic CoFe/Ni multilayers subject to a femtosecond optical pump were studied and it was shown that the domain dilation can be accelerated by 6% within 1.6 ps. This was based on the unambiguous determination of a harmonically-related shift of ultrafast magnetic X-ray diffraction for the first and third-order rings.

Comparison of measured and simulated spin-wave mode spectra of magnetic nanostructures
Hans T. Nembach,Hans T. Nembach,Robert D. McMichael,Michael L. Schneider,Justin M. Shaw,Thomas J. Silva +5 more
TL;DR: In this paper, the authors measured and modeled spin wave spectra in patterned elliptical nanomagnets and showed that the reduction of shape variations between individual magnetic random access memory elements can potentially improve their performance.

A microwave interferometer of the Michelson-type to improve the dynamic range of broadband ferromagnetic resonance measurements
TL;DR: In this paper, a Michelson-type microwave interferometer for use in ferromagnetic resonance experiments is presented, which is capable of broadband operation without manual adjustment of phase delay or amplitude attenuation.

Magnetic Article and Rotation of Magnetic Spins via Spin-Orbit Effect in Same
TL;DR: A nonvolatile memory cell includes: a first fixed magnetic layer, a first nonmagnetic electrode disposed on the first magnetic layer; a memory storage layer disposed on first non-magnetic electrodes; a tunnel barrier layer disposing on the memory storage layers; a second fixed magnet and a second non magnet on the tunnel barrier layers.

Development toward magneto-optic Kerr scanned near-field optical microscope with 10 nm resolution
Sheldon Schultz,Thomas J. Silva +1 more
TL;DR: Schultz et al. as discussed by the authors developed a magneto-optic Kerr scanned near-field optical microscope with 10 nm resolution, which can observe magnetization distributions with sub-wavelength resolution.
