Spatially resolved GHz magnetization dynamics of a magnetite nano-particle chain inside a magnetotactic bacterium

open access: yesPhysical Review Research, 2021
Understanding magnonic properties of nonperiodic magnetic nanostructures requires real-space imaging of ferromagnetic resonance modes with spatial resolution well below the optical diffraction limit and sampling rates in the 5–100 GHz range.

Resonance Frequency Tuning of a 200 GHz Band Absorber by an External Magnetic Field

open access: yesAdvanced Photonics Research, 2022
The effect of the external magnetic field on the millimeter‐wave absorption of rhodium‐substituted epsilon iron oxide, ε‐Rh0.13Fe1.87O3 (1) and ε‐Rh0.19Fe1.81O3 (2) nanomagnets, is investigated.

Ferromagnetic Resonance Studies in Magnetic Nanosystems

open access: yesMagnetochemistry, 2021
Ferromagnetic resonance is a powerful method for the study of all classes of magnetic materials. The experimental technique has been used for many decades and is based on the excitation of a magnetic spin system via a microwave (or rf) field.

Optimization of experiment settings in ferromagnetic resonance measurements

open access: yesResults in Physics, 2017
In a ferromagnetic resonance experiment, the frequency vs resonance field data is fitted to the resonance condition formula for extraction of the effective magnetization and gyromagnetic ratio of the ferromagnetic material under test.

Ferromagnetic Resonance of a [GeTe/Sb2Te3]6/Py Superlattice

open access: yesMagnetochemistry, 2021
A [GeTe/Sb2Te3] superlattice is known as a topological insulator. It shows magnetic responses such as magneto-optical effect, magneto resistance, magneto capacitance, and so on. We have reported that [GeTe/Sb2Te3] superlattice film has a large spin–orbit

Temperature dependence of Gilbert damping in manganite/normal metal heterostructure

open access: yesEPJ Web of Conferences, 2018
The temperature dependence of the spin-pumping effect on the Gilbert damping in a bilayer based on epitaxial manganite film grown on neodymium galate substrate was investigated by measuring of the linewidth of the ferromagnetic resonance spectrum (FMR ...

A quantum material spintronic resonator

open access: yesScientific Reports, 2021
In a spintronic resonator a radio-frequency signal excites spin dynamics that can be detected by the spin-diode effect. Such resonators are generally based on ferromagnetic metals and their responses to spin torques.

Thermoelectric Detection of Ferromagnetic Resonance of a Nanoscale Ferromagnet [PDF]

open access: yesPhysical Review Letters, 2012
We present thermoelectric measurements of the heat dissipated due to ferromagnetic resonance of a Permalloy strip. A microwave magnetic field, produced by an on-chip coplanar strip waveguide, is used to drive the magnetization precession. The generated heat is detected via Seebeck measurements on a thermocouple connected to the ferromagnet.

Ferromagnetic resonance and magnetic precessions in φ0 junctions

open access: yesPhysical review B, 2019
We show that a current sweep along the $IV$ curve of the ${\ensuremath{\varphi}}_{0}$ junction may lead to regular magnetization dynamics with a series of specific phase trajectories.
