A Survey of the Magnetic Anisotropy Detection Technology of Ferromagnetic Materials Based on Magnetic Barkhausen Noise [PDF]

Sensors
Magnetic Barkhausen noise (MBN) is one of the most effective methods for determining the easy axis of ferromagnetic materials and for evaluating texture and residual stress in a nondestructive manner.

Domain wall propagation in Fe-rich magnetic microwires with graded magnetic anisotropy

AIP Advances, 2022
We observed that stress-annealing of Fe75B9Si12C4 magnetic microwire at variable annealing temperature allows to create graded magnetic anisotropy. We have found that single domain wall (DW) propagation in a media with graded magnetic anisotropy is ...

X-ray Photoemission Spectroscopy Study of Uniaxial Magnetic Anisotropy Induced in a Ni Layer Deposited on a LiNbO₃ Substrate

Nanomaterials, 2021
The competition between magnetic shape anisotropy and the induced uniaxial magnetic anisotropy in the heterojunction between a ferromagnetic layer and a ferroelectric substrate serves to control magnetic domain structures as well as magnetization ...

Magnetic Anisotropy at Nanoscale [PDF]

Journal of Nanotechnology, 2011
Nanoscale objects often behave differently than their “normal-sized” counterparts. Sometimes it is enough to be small in just one direction to exhibit unusual features. One example of such a phenomenon is a very specific in-plane magnetic anisotropy observed sometimes in very thin layers of various materials.

Magnetic anisotropy of ultrathin Pd4Co(111) film by first-principles calculations

Journal of Science: Advanced Materials and Devices, 2018
The Pd–Co alloy is a suitable candidate for the perpendicular magnetic recording and related applications. However, no research is available to clarify influences of local structures on the magnetic anisotropy of the Pd–Co alloy. Therefore, in this work,

Competition of Magnetic Anisotropies in Permalloy Antidot Lattices

Magnetochemistry, 2022
Antidot lattices made of magnetic thin films are good candidates to be employed in future magnetic recording media. In this manuscript we present a study on the effect of shape and field-induced magnetic anisotropies on the magnetization reversal of 10 ...
