Mutual synchronization of constriction-based spin Hall nano-oscillators in weak in-plane fields
Hamid Mazraati, Shreyas Muralidhar, Seyyed Ruhollah Etesami +6
We study mutual synchronization in double nanoconstriction-based spin Hall nano-oscillators (SHNOs) under weak in-plane fields ( = 30-40 mT) and also investigate…
Mapping out the spin-wave modes of constriction-based spin Hall nano-oscillators in weak in-plane fields
Hamid Mazraati, Seyyed Ruhollah Etesami, Seyed Amir Hossein Banuazizi +5
We experimentally study the auto-oscillating spin-wave modes in NiFe/W constriction-based spin Hall nano-oscillators as a function of bias current, in-plane applied field stren…
Faster, farther, stronger: spin transfer torque driven high order propagating spin waves in nano-contact magnetic tunnel junctions
A. Houshang, R. Khymyn, M. Dvornik +6
Short wave-length exchange-dominated propagating spin waves will enable magnonic devices to operate at higher frequencies and higher data transmission rates.1 While GMR based magne…
Kinetics of nano-size Ferroelectrics
S. R. Etesami, A. Sukhov, J. Berakdar
We analyze theoretically the finite-temperature polarization dynamic in displacive-type ferroelectrics. In particular we consider the thermally-activated switching time of a single…
Efficient thermal energy harvesting using nanoscale magnetoelectric heterostructures
Seyyed Ruhollah Etesami, Jamal Berakdar
Thermomechanical cycles with a ferroelectric working substance convert heat to electrical energy. As shown here, magnetoelectrically coupled ferroelectric/ferromangtic composites (…
Electromagnetically controlled multiferroic thermal diode
L. Chotorlishvili, S. R. Etesami, J. Berakdar +2
We propose an electromagnetically tunable thermal diode based on a two phase multiferroics composite. Analytical and full numerical calculations for prototypical heterojunction com…
Spectral characteristics of time resolved magnonic spin Seebeck effect
S. R. Etesami, L. Chotorlishvili, J. Berakdar
Spin Seebeck effect (SSE) holds promise for new spintronic devices with low-energy consumption. The underlying physics, essential for a further progress, is yet to be fully clarifi…
Magnon-driven longitudinal spin Seebeck effect in F|N and N|F|N structures: role of asymmetric in-plane magnetic anisotropy
L. Chotorlishvili, Z. Toklikishvili, S. R. Etesami +3
The influence of an asymmetric in-plane magnetic anisotropy on the thermally activated spin current is studied theoretically for two different systems; (i) the system consisting of…
On the longitudinal spin current induced by a temperature gradient in a ferromagnetic insulator
S. R. Etesami, L. Chotorlishvili, A. Sukhov +1
Based on the solution of the stochastic Landau-Lifshitz-Gilbert equation discretized for a ferromagnetic chain subject to a uniform temperature gradient, we present a detailed nume…
