Determination of demagnetizing factors using first-order reversal curves and ferromagnetic resonance

AIP Advances, 2020
We present a method to quantitatively analyze magnetizing or demagnetizing interactions in arrayed nano-magnets by combining first-order reversal curve (FORC) and ferromagnetic resonance (FMR) measurement data.

Ultrafast demagnetizing fields from first principles [PDF]

Physical Review B, 2017
We examine the ultrafast demagnetization process of iron-based materials, namely, ${\mathrm{Fe}}_{6}$ clusters and bulk bcc Fe, with time-dependent spin-density functional theory (TDSDFT). The magnetization continuity equation is reformulated and the torque due to the spin-current divergence is written in terms of an effective time-dependent kinetic ...

The efficiency and the demagnetization field of a general Halbach cylinder [PDF]

, 2015
The maximum magnetic efficiency of a general multipole Halbach cylinder of order $p$ is found as function of $p$. The efficiency is shown to decrease for increasing absolute value of $p$. The optimal ratio between the inner and outer radius, i.e.

Ultrafast demagnetization in a ferrimagnet under electromagnetic field funneling [PDF]

Nanoscale, 2021
Bottom-up produced optical ring-shaped Ag nanoantennas efficiently funnel electromagnetic field of a femtosecond-pulsed laser light into a ferrimagnetic TbCo nanofilm at plasmon resonance. This leads to the TbCo demagnetization at the nanoscale.

Behavior of sensitivity at edge of thin-film magnetoimpedance element

AIP Advances, 2017
We fabricated thin-film magnetoimpedance elements in which an impedance of each 100 μm section of element can be examined, to investigate impedance changes of each section subjected to a DC magnetic field.

Dynamics of a ferromagnetic domain wall: avalanches, depinning transition and the Barkhausen effect [PDF]

, 1998
We study the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium. The avalanche-like motion of the domain walls between pinned configurations produces a noise known as the Barkhausen effect. We discuss
