Self-oscillations induced by self-induced torque in magnetic double tunnel junction
R. Arun, R. Gopal, V. K. Chandrasekar +1
Self-oscillations of the magnetization due to self-induced torque (SIT) in a magnetic double tunnel junction that consists of perpendicularly polarized, pinned and free layers is i…
Modulation of quantum geometry and its coupling to pseudo-electric field by dynamic strain
Surat Layek, Mahesh A. Hingankar, Ayshi Mukherjee +11
Two-dimensional materials are a fertile ground for exploring quantum geometric phenomena, with Berry curvature and its first moment, the Berry curvature dipole, playing a central r…
High frequency oscillations in spin-torque nano oscillator due to bilinear coupling
R. Arun, R. Gopal, V. K. Chandrasekar +1
Exchange coupling in an interfacial context is crucial for spin-torque nano oscillator (STNO) that consists of a non-magnetic spacer which is alloyed with a ferromagnetic material.…
Spin Torque Oscillations Triggered by In-plane Field
R. Arun, R. Gopal, V. K. Chandrasekar +1
We study the dynamics of a spin torque nano oscillator that consists of parallelly magnetized free and pinned layers by numerically solving the associated Landau-Lifshitz-Gilbert-S…
Frequency enhancement and power tunability in tilted polarizer spin-torque nano oscillator
R. Arun, 1 R. Gopal, V. K. Chandrasekar +1
In the absence of an applied magnetic field, a spin-torque nano oscillator(STNO) with a tilted polarizer is studied using numerical simulation of the associated Landau-Lifshitz-Gil…
Phase locking of spin transfer nano-oscillators using common microwave sources
R. Gopal, B. Subash, V. K. Chandrasekar +1
In this paper, we study typical nonlinear phenomenon of phase-locking or synchronization in spin-torque nano oscillators (STNOs). To start with the oscillators are considered as un…
