Reversible Magneto-ionic Modification of Metallic Magnetic Thin Films
Md Golam Hafiz, Hari Babu Vasili, Philippa Shepley +12
Magnetic multilayers with structural inversion asymmetry, perpendicular magnetic anisotropy (PMA), and large Dzyaloshinskii-Moriya interaction (DMI) are widely studied for magnetic…
Temperature dependence of magnetic anisotropy and domain wall tuning in BaTiO3(111)/CoFeB multiferroics
Robbie G. Hunt, Kévin J. A. Franke, Paul S. Keatley +3
Artificial multiferroics consist of two types of ferroic materials, typically a ferroelectric and ferromagnet, often coupled interfacially by magnetostriction induced by the lattic…
Strain Coupled Domains in BaTiO3(111)-CoFeB Heterostructures
Robbie G. Hunt, Kévin J. A. Franke, Philippa M. Shepley +1
Domain pattern transfer from ferroelectric to ferromagnetic materials is a critical step for the electric field control of magnetism and has the potential to provide new schemes fo…
Domain wall motion at low current density in a synthetic antiferromagnet nanowire
Christopher Barker, Simone Finizio, Eloi Haltz +6
The current-driven motion of magnetic domain walls (DWs) is the working principle of magnetic racetrack memories. In this type of spintronic technology, high current densities are…
Pt and CoB trilayer Josephson junctions with perpendicular magnetic anisotropy
N. Satchell, T. Mitchell, P. M. Shepley +3
We report on the electrical transport properties of Nb based Josephson junctions with Pt/CoB/Pt ferromagnetic barriers. The barriers exhibit perpendicular magnetic an…
Spin-valve Josephson junctions with perpendicular magnetic anisotropy for cryogenic memory
N. Satchell, P. M. Shepley, M. Algarni +8
We demonstrate a Josephson junction with a weak link containing two ferromagnets, with perpendicular magnetic anisotropy and independent switching fields in which the critical curr…
Dielectric properties of relaxor-ferroelectric ceramic and single crystal Pb(InNb)O-Pb(MgNb)O-PbTiO at cryogenic temperatures
Philippa M. Shepley, Laura A. Stoica, Yang Li +2
We investigate the low temperature behaviour of Pb(InNb)O-Pb(MgNb)O-PbTiO using dielectric permittivity measurements. We compare s…
Pinning and hysteresis in the field dependent diameter evolution of skyrmions in Pt/Co/Ir superlattice stacks
K. Zeissler, M. Mruczkiewicz, S. Finizio +10
We have imaged Néel skyrmion bubbles in perpendicularly magnetised polycrystalline multilayers patterned into 1 μm diameter dots, using scanning transmission x-ray microscopy. The…
Magnetic properties, domain wall creep motion and the Dzyaloshinskii-Moriya interaction in Pt/Co/Ir thin films
Philippa M. Shepley, Harry Tunnicliffe, Kowsar Shahbazi +2
We study the magnetic properties of perpendicularly magnetised Pt/Co/Ir thin films and investigate the domain wall creep method of determining the interfacial Dzyaloshinskii-Moriya…
Effect of interfacial intermixing on the Dzyaloshinskii-Moriya interaction in Pt/Co/Pt
Adam W. J. Wells, Philippa M. Shepley, Christopher H. Marrows +1
We study the effect of sputter-deposition conditions, namely substrate temperature and chamber base pressure, upon the interface quality of epitaxial Pt/Co/Pt thin films with perpe…
Effect of annealing on the interfacial Dzyaloshinskii-Moriya interaction in Ta/CoFeB/MgO trilayers
R. A. Khan, P. M. Shepley, A. Hrabec +4
The interfacial Dzyaloshinskii-Moriya interaction (DMI) has been shown to stabilize homochiral Néel-type domain walls in thin films with perpendicular magnetic anisotropy and as a…
Modification of perpendicular magnetic anisotropy and domain wall velocity in Pt/Co/Pt by voltage-induced strain
P. M. Shepley, A. W. Rushforth, M. Wang +2
The perpendicular magnetic anisotropy K, magnetization reversal, and field-driven domain wall velocity in the creep regime are modified in Pt/Co(0.85-1.0 nm)/Pt thin fi…
