Third Harmonic Characterization of Antiferromagnetic Heterostructures
Yang Cheng, Egecan Cogulu, Rachel D. Resnick +4
Electrical switching of antiferromagnets is an exciting recent development in spintronics, which promises active antiferromagnetic devices with high speed and low energy cost. In t…
Quantifying Spin-Orbit Torques in Antiferromagnet/Heavy Metal Heterostructures
Egecan Cogulu, Hantao Zhang, Nahuel N. Statuto +4
The effect of spin currents on the magnetic order of insulating antiferromagnets (AFMs) is of fundamental interest and can enable new applications. Toward this goal, characterizing…
Direct Imaging of Electrical Switching of Antiferromagnetic Néel Order in -FeO Epitaxial Films
Egecan Cogulu, Nahuel N. Statuto, Yang Cheng +4
We report the direct observation of switching of the Néel vector of antiferromagnetic (AFM) domains in response to electrical pulses in micron-scale Pt/-FeO Hall bars us…
Micromagnetic instabilities in spin-transfer switching of perpendicular magnetic tunnel junctions
Nahuel Statuto, Jamileh Beik Mohammadi, Andrew D. Kent
Micromagnetic instabilities and non-uniform magnetization states play a significant role in spin transfer induced switching of nanometer scale magnetic elements. Here we model doma…
Generation and annihilation time of magnetic droplet solitons
Jinting Hang, Christian Hahn, Nahuel Statuto +2
Magnetic droplet solitons were first predicted to occur in materials with uniaxial magnetic anisotropy due to a long-range attractive interaction between elementary magnetic excita…
Generation and stability of dynamical skyrmions and droplet solitons
Nahuel Statuto, Joan Manel Hernàndez, Andrew D. Kent +1
A spin-polarized current in a nanocontact to a magnetic film can create collective magnetic oscillations by compensating the magnetic damping. In particular, in materials with unia…
Switching of Magnetic Moments of Nanoparticles by Surface Acoustic Waves
J. Tejada, E. M. Chudnovsky, R. Zarzuela +4
We report evidence of the magnetization reversal in nanoparticles by surface acoustic waves (SAWs). The experimental system consists of isolated magnetite nanoparticles dispersed o…
Simultaneous imaging of strain waves and induced magnetization dynamics at the nanometer scale
Michael Foerster, Ferran Macià, Nahuel Statuto +8
Changes in strain can be used to modify electronic and magnetic properties in crystal structures, to manipulate nanoparticles and cells, or to control chemical reactions. The magne…
Narrow Zero-Field Tunneling Resonance in Triclinic Mn Acetate Ribbons
I. Imaz, J. Espin, D. Maspoch +4
We report synthesis, structural characterization, and magnetic measurements of amorphous Mn-acetate ribbons with a triclinic short-range crystal order not previously seen in…
Observation of droplet soliton drift resonances in a spin-transfer-torque nanocontact to a ferromagnetic thin film
Sergi Lendínez, Nahuel Statuto, Dirk Backes +2
Magnetic droplet solitons are non-linear dynamical modes that can be excited in a thin film with perpendicular magnetic anisotropy with a spin-transfer-torque. Although droplet sol…
