Observation of band narrowing and mode conversion in two-dimensional binary magnonic crystal
Nikita Porwal, Koustuv Dutta, Sucheta Mondal +4
We introduce a new type of binary magnonic crystal, where NiFe nanodots of two different sizes are diagonally connected forming a unit and those units are arranged in…

Observation of angle-dependent mode conversion and mode hopping in 2D annular antidot lattice
Nikita Porwal, Anulekha De, Sucheta Mondal +5
We report spin-wave excitations in annular antidot lattice fabricated from 15 nm-thin Ni80Fe20 flm. The nanodots of 170 nm diameters are embedded in the 350 nm (diameter) antidot l…

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…
