Journal Article
Gubbiotti, G., Zhou, X., Adeyeye, A., Varvaro, G., & Kostylev, M. (2020). Effect of exchange and dipolar interlayer interactions on the magnonic band structure of dense Fe/Cu/Py nanowires with symmetric and asymmetric layer widths. Physical Review B, 101(22), Article 224431. https://doi.org/10.1103/physrevb.101.224431

We present a systematic experimental and theoretical investigation of the magnonic band structure in dense arrays of both asymmetric and symmetric cross-section trilayered Fe(10 nm)/Cu( t )/Py(10 nm) nanowires (NWs). The Cu spacer thickness ( t ) is...

Constraints on the Velocity and Spin Dependent Exotic Interaction at the Micrometer Range (2020)
Journal Article
Ding, J., Wang, J., Zhou, X., Liu, Y., Sun, K., Adeyeye, A. O., Fu, H., Ren, X., Li, S., Luo, P., Lan, Z., Yang, S., & Luo, J. (2020). Constraints on the Velocity and Spin Dependent Exotic Interaction at the Micrometer Range. Physical Review Letters, 124(16), Article 161801. https://doi.org/10.1103/physrevlett.124.161801

We report on an experimental test of the velocity and spin dependent exotic interaction that can be mediated by new light bosons. The interaction is searched by measuring the force between a gold sphere and a microfabricated magnetic structure using...

Microwave assisted gating of spin wave propagation (2020)
Journal Article
Haldar, A., & Adeyeye, A. O. (2020). Microwave assisted gating of spin wave propagation. Applied Physics Letters, 116(16), Article 162403. https://doi.org/10.1063/5.0006945

Magnonics is an emerging research area where magnons or spin waves are used as a medium of information processing. Efficient manipulation/gating of magnons on-chip is crucial for realization of logic circuitry and device integration. Here, we show a...

Magnetic Tunability of Permalloy Artificial Spin Ice Structures (2020)
Journal Article
Talapatra, A., Singh, N., & Adeyeye, A. (2020). Magnetic Tunability of Permalloy Artificial Spin Ice Structures. Physical Review Applied, 13(1), Article 014034. https://doi.org/10.1103/physrevapplied.13.014034

This paper reports tunable Ni80Fe20 artificial spin ice structures of various geometrical lattice arrangements as a function of film thickness. We achieve the magnetic tunability by three distinct methods namely, geometrical arrangements of nanomagne... Read More about Magnetic Tunability of Permalloy Artificial Spin Ice Structures.

Direct mapping of spin wave modes of individual Ni80Fe20 nanorings (2020)
Journal Article
Tian, C., Chaudhuri, U., Singh, N., & Adeyeye, A. O. (2020). Direct mapping of spin wave modes of individual Ni80Fe20 nanorings. Nanotechnology, 31(14), Article 145714. https://doi.org/10.1088/1361-6528/ab662f

Ferromagnetic nanorings exhibit tunable magnetic states with unique magnetization reversal processes and dynamic behavior that can be exploited in data storage and magnonic devices. Traditionally, probing the magnetization dynamics of individual ferr... Read More about Direct mapping of spin wave modes of individual Ni80Fe20 nanorings.
