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…
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…
Nanochannels for Spin-Wave Manipulation in Ni80Fe20 Nanodot Arrays
Sourav Sahoo, Surya Narayan Panda, Saswati Barman +2
Patterned magnetic nanostructures are potential candidates for future energy efficient, on-chip communication devices. Here, we have experimentally and numerically studied the role…
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.…
The effect of material defects on resonant spin wave modes in a nanomagnet
Md Ahsanul Abeed, Sourav Sahoo, David Winters +2
We have theoretically studied how resonant spin wave modes in an elliptical nanomagnet are affected by fabrication defects, such as small local thickness variations. Our results in…
Fermi Level Controlled Ultrafast Demagnetization Mechanism in Half-Metallic Heusler Alloy
Santanu Pan, Takeshi Seki, Koki Takanashi +1
The electronic band structure-controlled ultrafast demagnetization mechanism in Co2FexMn1-xSi Heusler alloy is underpinned by systematic variation of composition. We find the spin-…
