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…
All-optical Detection of Spin Hall Angle in W/CoFeB/SiO2 Heterostructures by Varying Tungsten Layer Thickness
Sucheta Mondal, Samiran Choudhury, Neha Jha +3
The development of advanced spintronics devices hinges on the efficient generation and utilization of pure spin current. In materials with large spin-orbit coupling, the spin Hall…
Spin orbit effects in CoFeB/MgO hetereostructures with heavy metal underlayers
Jacob Torrejon, Junyeon Kim, Jaivardhan Sinha +1
We study effects originating from the strong spin orbit coupling in CoFeB/MgO heterostructures with heavy metal (HM) underlayers. The perpendicular magnetic anisotropy at the CoFeB…
