The effect of material defects on resonant spin wave modes in a nanomagnet
Md Ahsanul Abeed, Sourav Sahoo, David Winters +2
We have theoretically studied how resonant spin wave modes in an elliptical nanomagnet are affected by fabrication defects, such as small local thickness variations. Our results in…
Tunability of domain structure and magnonic spectra in antidot arrays of Heusler alloy
Sougata Mallick, Sucheta Mondal, Takeshi Seki +8
Materials suitable for magnonic crystals demand low magnetic damping and long spin wave (SW) propagation distance. In this context Co based Heusler compounds are ideal candidates f…
Error Probability in Magneto-elastic Switching of Non-ideal Nanomagnets with Defects: A Case Study for the Viability of Straintronic Logic and Memory
David Winters, Md Ahsanul Abeed, Sourav Sahoo +2
Magneto-elastic (straintronic) switching of bistable magnetostrictive nanomagnets is an extremely energy-efficient switching methodology for (magnetic) binary switches that has rec…
Hybrid magneto-dynamical modes in a single magnetostrictive nanomagnet on a piezoelectric substrate arising from magneto-elastic modulation of precessional dynamics
Sucheta Mondal, Md Ahsanul Abeed, Koustuv Dutta +4
Magneto-elastic (or "straintronic") switching has emerged as an extremely energy-efficient mechanism for switching the magnetization of magnetostrictive nanomagnets in magnetic mem…
