Structural Design of Demagnetization Detection Robot in Oil and Gas Pipeline

Shiyou jixie, 2020
The oil and gas pipelines in service will produce certain residual magnetism due to the influence of various factors. To quickly and efficiently eliminate the residual magnetism, according to the theory of dynamic demagnetization of permanent magnets, a ...

Ultrafast demagnetization by hot electrons: Diffusion or super-diffusion?

Structural Dynamics, 2016
Ultrafast demagnetization of ferromagnetic metals can be achieved by a heat pulse propagating in the electron gas of a non-magnetic metal layer, which absorbs a pump laser pulse.

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Broadening Hard‐Magnet Discovery Beyond Symmetry Constraints via Unified Effective Anisotropy

Advanced Science, EarlyView.
A unified effective‐anisotropy descriptor (Keff) extends hard‐magnet screening across all seven crystal systems, beyond the uniaxial restriction of conventional searches. Machine‐learning screening of 9320 known ferromagnets and diffusion‐model generation together yield 38 rare‐earth‐free or ‐lean candidates with DFT‐validated magnetic hardness (κ > 1),

Correction to “Micromagnetic models of pseudo-single domain grains of magnetite near the Verwey Transition” [PDF]

, 1999
Domain structures of small pseudo-single domain (PSD) magnetite near the Verwey transition (Tυ) at ≈120 K were modeled using an unconstrained three-dimensional micromagnetic algorithm.

Nuclear demagnetization for ultra-low temperatures [PDF]

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 ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
