Temperature dependence of the interface spin Seebeck effect
F. N. Kholid, D. Hamara, M. Terschanski +10
We performed temperature-dependent optical pump - THz emission measurements in Y3Fe5O12 (YIG)|Pt from 5 K to room temperature in the presence of an externally applied magnetic fiel…
Intra-wire coupling in segmented Ni/Cu nanowires deposited by electrodeposition
Philip Sergelius, Ji Lee, Olivier Fruchart +18
Segmented magnetic nanowires are a promising route for the development of three dimensional data storage techniques. Such devices require a control of the coercive field and the co…
Manipulation of Magnetic Solitons on Odd-Numbered Macrospin Rings
J. P. Morgan, R. P. Cowburn
We report simulations of a frustrated odd-numbered macrospin ring system, with full point dipolar interactions, driven by a rotating uniform applied magnetic field of constant magn…
Resonance in Magnetostatically Coupled Transverse Domain Walls
Andrew T. Galkiewicz, Liam O'Brien, Paul S. Keatley +2
We have observed the eigenmodes of coupled transverse domain walls in a pair of ferromagnetic nanowires. Although the pair is coupled magnetostatically, its spectrum is determined…
Coupling and induced depinning of magnetic domain walls in adjacent spin valve nanotracks
J. Sampaio, L. O'Brien, D. Petit +6
The magnetostatic interaction between magnetic domain walls (DWs) in adjacent nanotracks has been shown to produce strong inter-DW coupling and mutual pinning. In this paper, we ha…
Macrospin limit and configurational anisotropy in nanoscale Permalloy triangles
Laura Thevenard, Huang Tao Zeng, Dorothée Petit +1
In Permalloy submicron triangles, configurational anisotropy - a higher-order form of shape anisotropy - yields three equivalent easy axes, imposed by the structures' symmetry orde…
Six-fold configurational anisotropy and magnetic reversal in nanoscale Permalloy triangles
Laura Thevenard, Dorothee Petit, Huang T. Zeng +1
Six-fold configurational anisotropy was studied in Permalloy triangles, in which the shape symmetry order yields two energetically non-degenerate micromagnetic configurations of th…
Near-field interaction between domain walls in adjacent Permalloy nanowires
Liam O'Brien, D. Petit, H. T. Zeng +5
The magnetostatic interaction between two oppositely charged transverse domain walls (DWs)in adjacent Permalloy nanowires is experimentally demonstrated. The dependence of the pinn…
Domain wall pinning and potential landscapes created by constrictions and protrusions in ferromagnetic nanowires
Dorothee Petit, Ana-Vanessa Jausovec, Dan Read +1
The potential experienced by transverse domain walls (TDWs) in the vicinity of asymmetric constrictions or protrusions in thin Permalloy nanowires is probed using spatially resolve…
Domain wall propagation in magnetic nanowires by spin polarized current injection
Nicolas Vernier, Dan A. Allwood, Del Atkinson +2
We demonstrate movement of a head-to-head domain wall through a magnetic nanowire simply by passing an electrical current through the domain wall and without any external magnetic…
