Binary switching in a symmetric potential landscape
Kuntal Roy, Supriyo Bandyopadhyay, Jayasimha Atulasimha
The general methodology of binary switching requires tilting of potential landscape along the desired direction of switching. The tilt generates a torque along the direction of swi…
Energy dissipation and switching delay in stress-induced switching of multiferroic devices in the presence of thermal fluctuations
Kuntal Roy, Supriyo Bandyopadhyay, Jayasimha Atulasimha
Switching the magnetization of a shape-anisotropic 2-phase multiferroic nanomagnet with voltage-generated stress is known to dissipate very little energy ( 1 aJ for a switching…
Energy dissipation and switching delay in spin-transfer torque switching of nanomagnets with low-saturation magnetization in the presence of thermal fluctuations
Kuntal Roy, Supriyo Bandyopadhyay, Jayasimha Atulasimha +2
A common ploy to reduce the switching current and energy dissipation in spin-transfer-torque driven magnetization switching of shape-anisotropic single-domain nanomagnets is to emp…
Metastable state in a shape-anisotropic single-domain nanomagnet subjected to spin-transfer-torque
Kuntal Roy, Supriyo Bandyopadhyay, Jayasimha Atulasimha
We predict the existence of a new metastable magnetization state in a single-domain nanomagnet with uniaxial shape anisotropy. It emerges when a spin-polarized current, delivering…
Switching dynamics of a magnetostrictive single-domain nanomagnet subjected to stress
Kuntal Roy, Supriyo Bandyopadhyay, Jayasimha Atulasimha
The temporal evolution of the magnetization vector of a single-domain magnetostrictive nanomagnet, subjected to in-plane stress, is studied by solving the Landau-Lifshitz-Gilbert e…
Hybrid spintronics and straintronics: A magnetic technology for ultra low energy computing and signal processing
Kuntal Roy, Supriyo Bandyopadhyay, Jayasimha Atulasimha
The authors show that the magnetization of a magnetostrictive/piezoelectric multiferroic single-domain shape-anisotropic nanomagnet can be switched with very small voltages that ge…
