Interface-Controlled Spin-Orbit Torques in Rare-Earth Synthetic Ferrimagnets Probed by Sagnac Magneto-Optics and Harmonic Hall Measurements
Akilan K, Koral Aykin, Jose-Luis Ampuero +6
Spin-orbit torque (SOT) provides an efficient route for manipulating magnetization in spintronic devices, and its accurate quantification is essential. Here, we investigate Co/Gd-b…
Transient Magnetoelastic Coupling in CrSBr
Youn Jue Bae, Taketo Handa, Yanan Dai +10
Recent research has revealed remarkable properties of the two-dimensional (2D) van der Waals layered crystal CrSBr, which is both a semiconductor and an A-type antiferromagnet. Her…
Energy Barriers for Thermally Activated Magnetization Reversal in Perpendicularly Magnetized Nanodisks in a Transverse Field
Corrado Carlo Maria Capriata, Bengt Gunnar Malm, Andrew D. Kent +1
Thermally-induced transitions between bistable magnetic states of magnetic tunnel junctions (MTJ) are of interest for generating random bitstreams and for applications in stochasti…
Large Fluctuations and Singular Behavior of Nonequilibrium Systems
Daniele Pinna, Andrew D. Kent, Daniel L. Stein
We present a general geometrical approach to the problem of escape from a metastable state in the presence of noise. The accompanying analysis leads to a simple condition, based on…
X-Ray Detection of Transient Magnetic Moments Induced by a Spin Current in Cu
R. Kukreja, S. Bonetti, Z. Chen +7
We have used a MHz lock-in x-ray spectro-microscopy technique to directly detect changes of magnetic moments in Cu due to spin injection from an adjacent Co layer. The elemental an…
Spin wave excitation patterns generated by spin torque oscillators
Ferran Macià, Frank. C. Hoppensteadt, Andrew D. Kent
Spin torque nano oscillators (STNO) are nano-scale devices that can convert a direct current into short wave-length spin-wave excitations in a ferromagnetic layer. We show that arr…
FLUXCAP: A flux-coupled ac/dc magnetizing device
Daniel B. Gopman, Huanlong Liu, Andrew D. Kent
We report on an instrument for applying ac and dc magnetic fields by capturing the flux from a rotating permanent magnet and projecting it between two adjustable pole pieces. This…
Thermal Stability of the Magnetization in Perpendicularly Magnetized Thin Film Nanomagnets
Gabriel D. Chaves-OFlynn, Eric Vanden-Eijnden, D. L. Stein +1
Understanding the stability of thin film nanomagnets with perpendicular magnetic anisotropy (PMA) against thermally induced magnetization reversal is important when designing perpe…
Annular Spin-Transfer Memory Element
Andrew D. Kent, Daniel L. Stein
An annular magnetic memory that uses a spin-polarized current to switch the magnetization direction or helicity of a magnetic region is proposed. The device has magnetic materials…
Ferromagnetic resonance linewidth in ultrathin films with perpendicular magnetic anisotropy
J-M. Beaujour, D. Ravelosona, I. Tudosa +2
Transition metal ferromagnetic films with perpendicular magnetic anisotropy (PMA) have ferromagnetic resonance (FMR) linewidths that are one order of magnitude larger than soft mag…
Current-Induced Effective Magnetic Fields in Co/Cu/Co Nanopillars
M. A. Zimmler, B. Özyilmaz, W. Chen +4
We present a method to measure the effective field contribution to spin-transfer-induced interactions between the magnetic layers in a trilayer nanostructure, which enables spin-cu…
