electric-field control of ferromagnetic resonance in the low-loss organic-based ferrimagnet V[TCNE]
Seth W. Kurfman, Andrew Franson, Piyush Shah +10
We demonstrate indirect electric-field control of ferromagnetic resonance (FMR) in devices that integrate the low-loss, molecule-based, room-temperature ferrimagnet vanadium tetrac…
Symmetry and nonlinearity of spin wave resonance excited by focused surface acoustic waves
Piyush J. Shah, Derek A. Bas, Abbass Hamadeh +6
The use of a complex ferromagnetic system to manipulate GHz surface acoustic waves is a rich current topic under investigation, but the high-power nonlinear regime is under-explore…
Interface Engineering Enabled Low Temperature Growth of Magnetic Insulator on Topological Insulator
Nirjhar Bhattacharjee, Krishnamurthy Mahalingam, Alexandria Will-Cole +7
Combining topological insulators (TIs) and magnetic materials in heterostructures is crucial for advancing spin-based electronics. Magnetic insulators (MIs) can be deposited on TIs…
Effects of Crystalline Disorder on Interfacial and Magnetic Properties of Sputtered Topological Insulator/Ferromagnet Heterostructures
Nirjhar Bhattacharjee, Krishnamurthy Mahalingam, Adrian Fedorko +7
Thin films of Topological insulators (TIs) coupled with ferromagnets (FMs) are excellent candidates for energy-efficient spintronics devices. Here, the effect of crystalline struct…
Antiferromagnetic VdW Phase at the Interface of Sputtered Topological Insulator/Ferromagnet-Bi2Te3/Ni80Fe20 Heterostructures
Nirjhar Bhattacharjee, Krishnamurthy Mahalingam, Adrian Fedorko +11
Magnetic ordering in topological insulators (TI) is crucial for breaking time-reversal symmetry (TRS) and thereby opening a gap in the topological surface states (TSSs) [1-6], whic…
Giant Nonreciprocity of Surface Acoustic Waves enabled by the Magnetoelastic Interaction
Piyush J. Shah, Derek A. Bas, Ivan Lisenkov +3
Nonreciprocity, the defining characteristic of isolators, circulators and a wealth of other applications in radio/microwave communications technologies, is in general difficult to…
Ferromagnetic dynamics detected via one- and two-magnon NV relaxometry
Brendan A. McCullian, Ahmed M. Thabt, Benjamin A. Gray +7
The NV center in diamond has proven to be a powerful tool for locally characterizing the magnetic response of microwave excited ferromagnets. To date, this has been limited by the…
Increased low-temperature damping in yttrium iron garnet thin films
C. L. Jermain, S. V. Aradhya, J. T. Brangham +6
We report measurements of the frequency and temperature dependence of ferromagnetic resonance (FMR) for a 15-nm-thick yttrium iron garnet (YIG) film grown by off-axis sputtering. A…

Michael R. Page, Feng Guo, Carola M. Purser +7
We report quantitative measurements of optically detected ferromagnetic resonance (ODFMR) of ferromagnetic thin films that use nitrogen-vacancy (NV) centers in diamonds to transduc…
Correlating spin transport and electrode magnetization in a graphene spin valve: simultaneous magnetic microscopy and non-local measurements
Andrew J. Berger, Michael R. Page, Hua Wen +4
Using simultaneous magnetic force microscopy (MFM) and transport measurements of a graphene spin valve, we correlate the non-local spin signal with the magnetization of the device…
