Effects of the removal of Ta capping layer on the magnetization dynamics of Permalloy thin films
Nikita Porwal, Simone Peli, P. J. Chen +2
We have investigated the spin wave dynamics of Permalloy (Py) thin films with and without a Ta capping layer for varying Py thickness (15 nm, 20 nm and 30 nm) using all optical tim…
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…
Effects of Nanodots Shape and Lattice Constants on the Spin Wave Dynamics of Patterned Permalloy Dots
Nikita Porwal, Jaivardhan Sinha, Prasanta Kumar Datta
Micromagnetic simulations studies on Permalloy (Ni80Fe20) nanodot with different shape and edge-to-edge separation (s) down to 25nm arranged in square lattice are reported. We obse…
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…
