Excited State Spectroscopy of Boron Vacancy Defects in Hexagonal Boron Nitride using Time-Resolved Optically Detected Magnetic Resonance
Simon Baber, Ralph N. E. Malein, Prince Khatri +5
We report optically detected magnetic resonance (ODMR) measurements of an ensemble of spin-1 negatively charged boron vacancies in hexagonal boron nitride. The photoluminescence de…
Time-domain imaging of curling modes in a confined magnetic vortex and a micromagnetic study exploring the role of spiral spin waves emitted by the core
D. Osuna Ruiz, P. S. Keatley, J. R. Childress +4
The curling spin wave modes of a ferromagnetic vortex confined to a microscale disc have been directly imaged in response to a microwave field excitation using time-resolved scanni…
Interplay between spin proximity effect and charge-dependent exciton dynamics in MoSe / CrBr van der Waals heterostructures
T. P. Lyons, D. Gillard, A. Molina-Sánchez +9
Semiconducting ferromagnet-nonmagnet interfaces in van der Waals heterostructures present a unique opportunity to investigate magnetic proximity interactions dependent upon a multi…
Graphene Overcoats for Ultra-High Storage Density Magnetic Media
N. Dwivedi, A. K. Ott, K. Sasikumar +10
Hard disk drives (HDDs) are used as secondary storage in a number of digital electronic devices owing to low cost (0.1$/GB at 2016 prices) and large data storage capacity (10TB…
Time resolved imaging of the non-linear bullet mode within an injection-locked nano-contact spin Hall nano-oscillator
Timothy M Spicer, Paul S Keatley, Mykola Dvornik +8
Injection of a radio frequency (RF) current was used to phase lock the SHNO to the TRSKM. The out of plane magnetization was detected by means of the polar magneto optical Kerr eff…
Spatial Mapping of Torques within a Spin Hall Nano-oscillator
Timothy M Spicer, Paul S Keatley, Thomas H J Loughran +8
Time-resolved scanning Kerr microscopy (TRSKM) was used to study precessional magnetization dynamics induced by a radio frequency (RF) current within a AlO/Py(5 nm)/Pt(6 nm…
A platform for time-resolved scanning Kerr microscopy in the near-field
Paul S. Keatley, Thomas H. J. Loughran, Euan Hendry +4
Time-resolved scanning Kerr microscopy (TRSKM) is a powerful technique for the investigation of picosecond magnetization dynamics at sub-micron length scales by means of the magnet…
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…
Time-resolved investigation of magnetization dynamics of arrays of non-ellipsoidal nanomagnets with a non-uniform ground state
P. S. Keatley, V. V. Kruglyak, A. Neudert +4
We have performed time-resolved scanning Kerr microscopy (TRSKM) measurements upon arrays of square ferromagnetic nano-elements of different size and for a range of bias fields. Th…
