Coherent and incoherent magnons induced by strong ultrafast demagnetization in thin permalloy films
Anulekha De, Akira Lentfert, Laura Scheuer +4
Understanding spin dynamics on femto- and picosecond timescales offers new opportunities for faster and more efficient spintronic devices. Here, we experimentally investigate the c…
Coherent magnetization dynamics in strongly quenched Ni thin films
Akira Lentfert, Anulekha De, Laura Scheuer +4
The remagnetization process after ultrafast demagnetization can be described by relaxation mechanisms between the spin, electron, and lattice reservoirs. Thereby, collective spin e…
Magnetization Dynamics of Nanoscale Magnetic Materials: A Perspective
Anjan Barman, Sucheta Mondal, Sourav Sahoo +1
Nanomagnets form the building blocks for a gamut of miniaturized energy-efficient devices including data storage, memory, wave-based computing, sensors and biomedical devices. They…
Extreme sub-wavelength magneto-elastic electromagnetic antenna implemented with multiferroic nanomagnets
J. L. Drobitch, A. De, K. Dutta +4
Antennas typically have emission/radiation efficiencies bounded by A/(lambda)^2 (A < lambda^2) where A is the emitting area and lambda is the wavelength of the emitted wavelength.…
All optical detection of picosecond spin-wave dynamics in two-dimensional annular antidot lattice
Nikita Porwal, Sucheta Mondal, Samiran Choudhury +4
Novel magnetic structures with precisely controlled dimensions and shapes at the nanoscale have potential applications in spin logic, spintronics and other spin-based communication…
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…
