4D Printing of Multimaterial Flexible Magneto‐Active Polymers

open access: yesAdvanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

Ultrafast dynamics of 4f electron spins in TbFeCo film driven by inter-atomic 3d–5d–4f exchange coupling

open access: yesNew Journal of Physics, 2019
The ultrafast demagnetization dynamics of 3d and 4f spins, respectively, in FeCo and Tb of TbFeCo alloy film are studied independently by employing a dual-color time-resolved magneto-optical Kerr spectroscopy.

Design and optimization of processes for recovering rare earth elements from end‐of‐life permanent magnets

open access: yesAIChE Journal, Volume 72, Issue 5, May 2026.
Abstract Recovery of rare earth elements (REEs) from end‐of‐life (EOL) products represents a strategic opportunity to strengthen the domestic supply chain for rare earth elements. This work presents a superstructure‐based optimization framework for finding the most economical processing pathway for different EOL rare earth permanent magnets (REPMs ...

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Dependence Influence of Electro-Magnetic Field Parameters Demagnetization Quality of Ferro-Magnetic Bodies on Initial Value of Demagnetizing Field

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2010
The paper has experimentally determined that while demagnetizing ferro-magnetic bodies value of residual demagnetization depends on the first impulse amplitude of  the demagnetizing field.

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.
