Micromagnetic simulations of spin-torque driven magnetisation dynamics with spatially resolved spin transport and magnetisation texture
Simone Borlenghi, M. R. Mahani, Hans Fangohr +3
We present a simple and fast method to simulate spin-torque driven magnetisation dynamics in nano-pillar spin-valve structures. The approach is based on the coupling between a spin…
Proposal of a micromagnetic standard problem for ferromagnetic resonance simulations
Alexander Baker, Marijan Beg, Gregory Ashton +10
Nowadays, micromagnetic simulations are a common tool for studying a wide range of different magnetic phenomena, including the ferromagnetic resonance. A technique for evaluating r…
Nmag micromagnetic simulation tool - software engineering lessons learned
Hans Fangohr, Maximilian Albert, Matteo Franchin
We review design and development decisions and their impact for the open source code Nmag from a software engineering in computational science point of view. We summarise lessons l…
Mesh Size and Damped Edge Effects in Micromagnetic Spin Wave Simulation
G. Venkat, M. Franchin, H. Fangohr +1
We have studied the dependence of spin wave dispersion on the characteristics of the mesh used in a finite element micromagnetic simulation. It is shown that the dispersion curve h…
Thermally excited spin waves in a nano-structure: thermal gradient vs. constant temperature
Simone Borlenghi, Matteo Franchin, Hans Fangohr +2
Using micromagnetic simulations, we have investigated spin dynamics in a nanostructure in the presence of thermal fluctuations. In particular, we have studied the effects of a unif…
Spin wave amplification driven by heat flow: the role of damping and exchange interaction
S. Borlenghi, M. Franchin, H. Fangohr +2
In this article we report on micromagnetic simulations performed on a permalloy nanostructure in presence of a uniform thermal gradient. Our numerical simulations show that heat fl…
High frequency permeability of magnonic metamaterials with magnetic inclusions of complex shape
O. Dmytriiev, M. Dvornik, R. V. Mikhaylovskiy +9
We present a method of calculation of the effective magnetic permeability of magnonic metamaterials containing periodically arranged magnetic inclusions of arbitrary shapes. The sp…
Enhanced spin transfer torque effect for transverse domain walls in cylindrical nanowires
Matteo Franchin, Andreas Knittel, Maximilian Albert +4
Recent studies have predicted extraordinary properties for transverse domain walls in cylindrical nanowires: zero depinning current, the absence of the Walker breakdown, and applic…
Joule heating in nanowires
Hans Fangohr, Dmitri S. Chernyshenko, Matteo Franchin +2
We study the effect of Joule heating from electric currents flowing through ferromagnetic nanowires on the temperature of the nanowires and on the temperature of the substrate on w…
