Fault Diagnosis Method for DC Current Transformers Based on Deep Learning Hybrid Model

open access: yesVector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
Aiming at the problems of scarce fault samples, strong noise interference and complex feature coupling in the current DCCT fault diagnosis process, a DCCT fault diagnosis method based on a hybrid deep learning model is proposed. The performance of the proposed method is verified through experiments.

Nuclear demagnetization for ultra-low temperatures [PDF]

open access: yes
Nuclear demagnetization is one of the most successful methods of cooling an appreciable amount of matter to the lowest temperatures. The principle of nuclear demagnetization is the same as that of the adiabatic demagnetization of a paramagnetic salt ...

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

open access: yesAdvanced Science, Volume 13, Issue 62, 9 November 2026.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

Advances in High‐Temperature Microwave‐Absorbing Materials With Rare Metals: Preparations, Classifications, and Strategies

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT High‐temperature microwave‐absorbing materials (HTMAMs) are vital for the electromagnetic stealth of hypersonic aircraft and aerospace engines. Traditional carbon‐based or magnetic‐based absorbers suffer from oxidation, Curie‐temperature limitations, and impedance mismatch under extreme conditions.

Dependence of Demagnetization Quality of Ferromagnetic Bodies on Frequency Relationship and Duration of Demagnetization Process

open access: yes, 2007
Experiments have revealed that demagnetization quality of ferromagnetic bodies depends on characteristics of demagnetizing field that are determined by their size and internal properties.

Demagnetization factors and field of hemispherical objects

open access: yes
Demagnetization factors play an important role in micromagnetics modeling but exact solutions only exist for a limited number of particle shapes. Here we use a Fourier space based approach coupled to the concept of magnetic charges to derive analytically
