Tunable Strong Magnon-Magnon Coupling in Two-Dimensional Array of Diamond Shaped Ferromagnetic Nanodots
Sudip Majumder1, Samiran Choudhury1, Saswati Barman2 +3
Hybrid magnonics involving coupling between magnons and different quantum particles have been extensively studied during past few years for varied interests including quantum elect…
Structural Phase Dependent Giant Interfacial Spin Transparency in W/CoFeB Thin Film Heterostructure
Surya Narayan Panda, Sudip Majumder, Arpan Bhattacharyya +3
Pure spin current has transfigured the energy-efficient spintronic devices and it has the salient characteristic of transport of the spin angular momentum. Spin pumping is a potent…
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…
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…
Active Control of Mode Crossover and Mode Hopping of Spin Waves in a Ferromagnetic Antidot Lattice
Samiran Choudhury, Sudip Majumder, Saswati Barman +2
Active control of spin-wave dynamics is demonstrated using broadband ferromagnetic resonance in two-dimensional Ni80Fe20 antidot lattices arranged in hexagonal lattice with fixed 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…
