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.

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.

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.

Edge Engineering in MoS2 by Chemically Induced Nano‐Folding

Small Structures, Volume 6, Issue 9, September 2025.
By utilizing a buffered oxide etchant solution, nano‐folding in MoS2 flakes is induced, resulting in controlled detachment and the formation of additional active edges. This study introduces a straightforward technique for edge engineering in MoS2 flakes through chemically induced nano‐folding.

Analysis of Paleointensity Results Under Different Interpretation Approaches: A Case Study on the Korkhi Volcanic Sequence (Lesser Caucasus, Georgia)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract In this study we focus on the investigation of the absolute intensity records of two volcanic subsequences, aiming to enrich the global paleointensity database for the last 5 Ma, which currently shows important dispersion. We present new absolute paleointensities obtained from the Plio‐Pleistocene volcanic sequence of Korkhi (Djavakheti ...

Magnetismo em materiais orgânicos

Brazilian Journal of Development, 2023
As propriedades magnéticas de pastilhas prensadas de poli (3-hexiltiofeno) (P3HT) parcialmente dopado com o íon  foram estudadas na faixa de 5 a 300 K, e uma fase ferromagnética foi observada à temperatura ambiente. A origem do momento magnético no P3HT e sua interação ferromagnética estão relacionadas à formação de polarons na cadeia polimérica ...
