Interplay Between Structure and Interfacial Interactions in Fe‐Gd Synthetic Ferrimagnets

Advanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.
Synthetic ferrimagnets with nearly identical Gd–Fe compositions but different architectures and crystallinity were investigated by element‐resolved microscopy, structural analysis and atomistic spin simulations. The results show that Curie temperature and domain evolution are governed primarily by structural order and interface quality, demonstrating ...

Influence of Various Heat Treatments on Giant Magnetoimpedance Effect in Nanocrystalline FeSiBNbCu Ribbons

Texture, Stress, and Microstructure, Volume 32, Issue 1-4, Page 269-279, 1999., 1997
In this paper we present studies on the frequency dependence of the magneto‐impedance in the range of 0.1–2 MHz for Fe73.5Si13.5B9Nb3Cu1 and Fe73.5Si16.5B6Nb3Cu1 nanocrystalline ribbons, which differ in the sign of the magnetostriction constant. As cast samples were annealed in Ar atmosphere at 560℃, with and without an DC and AC magnetic field.

Colossal anisotropy in diluted magnetic topological insulators [PDF]

, 2010
We consider dilute magnetic doping in the surface of a three dimensional topological insulator where a two dimensional Dirac electron gas resides. We find that exchange coupling between magnetic atoms and the Dirac electrons has a strong and peculiar ...

High Magnetic Sensitivity at the Coercive Field Induced by Shear Horizontal SAW in Polycrystalline FeGa Films

Advanced Materials Technologies, Volume 10, Issue 18, September 18, 2025.
A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.

Anomalies in the magnetostrictive modulation of love surface acoustic waves

AIP Advances
A magnetic surface acoustic wave (SAW) sensor is built by growing a 100 nm galfenol (Fe72Ga28) film by sputtering between the interdigitated transducers of a SAW delay line.
