Nanoscale magnetization and current imaging using scanning-probe magneto-thermal microscopy
Chi Zhang, Jason M. Bartell, Jonathan C. Karsch +2
Magnetic microscopy that combines nanoscale spatial resolution with picosecond scale temporal resolution uniquely enables direct observation of the spatiotemporal magnetic phenomen…
Table-top Measurement of Local Magnetization Dynamics Using Picosecond Thermal Gradients: Toward Nanoscale Magnetic Imaging
J. M. Bartell, D. H. Ngai, Z. Leng +1
Recent advances in nanoscale magnetism have demonstrated the potential for spin-based technology including magnetic random access memory, nanoscale microwave sources, and ultra-low…
Perpendicular Magnetization and Generic Realization of the Ising Model in Artificial Spin Ice
Sheng Zhang, Jie Li, Ian Gilbert +11
We have studied frustrated kagome arrays and unfrustrated honeycomb arrays of magnetostatically-interacting single-domain ferromagnetic islands with magnetization normal to the pla…
Magnetization states and switching in narrow-gapped ferromagnetic nanorings
Jie Li, Sheng Zhang, Chris Grigas +4
We study permalloy nanorings that are lithographically fabricated with narrow gaps that break the rotational symmetry of the ring while retaining the vortex ground state, using bot…
Ignoring your neighbors: Moment correlations dominated by indirect or distant interactions in an ordered nanomagnet array
Sheng Zhang, Jie Li, Jason Bartell +5
We have studied the moment correlations within triangular lattice arrays of single-domain co-aligned nanoscale ferromagnetic islands. Independent variation of lattice spacing along…
