The correction of instrument transformer ferroresonance model in IEC standard and study on resonance interval based on transformer damping

AIP Advances, 2023
The traditional ferromagnetic resonance model of the inductive voltage transformer in the IEC/TR 61869-102 transformer standard ignores the DC resistance of the transformer.

On-chip detection of ferromagnetic resonance of a single submicron permalloy strip [PDF]

, 2006
We measured ferromagnetic resonance of a single submicron ferromagnetic strip, embedded in an on-chip microwave transmission line device. The method used is based on detection of the oscillating magnetic flux due to the magnetization dynamics, with an ...

Spin–orbit-driven ferromagnetic resonance [PDF]

Nature Nanotechnology, 2011
Ferromagnetic resonance is the most widely used technique for characterizing ferromagnetic materials. However, its use is generally restricted to wafer-scale samples or specific micro-magnetic devices, such as spin valves, which have a spatially varying magnetization profile and where ferromagnetic resonance can be induced by an alternating current ...

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

Physical 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.

Ferromagnetic Resonance Studies in Magnetic Nanosystems

Magnetochemistry, 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

Results 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

Magnetochemistry, 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

EPJ 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 ...

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

Physical 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.
