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),

MICROMAGNETIC SIMULATION OF MAGNETIZATION PROCESSES IN ANTIFERROMAGNETIC THIN FILMS [PDF]

, 2023
In this work we use the OOMMF micromagnetic simulation package to simulate magnetization processes in antiferromagnetic thin films. The influence of the magnetic anisotropy constant and exchange stiffness of the antiferromagnet on the magnetic ...

A Gauss–Seidel Projection Method for Micromagnetics Simulations [PDF]

Journal of Computational Physics, 2001
The dynamics of the magnetization distribution in a ferromagnetic thin film problem is studied in this paper. The relaxation process of the magnetization distribution in a ferromagnetic material is described by the Landau-Lifshitz equation for the saturation magnetization \(M = M(t)\). On of the main difficulties in micromagnetic simulation is a severe

Domain wall creep motion dynamics in CoFeB nanowire strips of different thicknesses using micromagnetic simulation approach [PDF]

ITM Web of Conferences
Field-induced domain wall motion on thin magnetic films with perpendicular anisotropy has long been attributed with the universal creep theory, in which the domain wall (DW) is able to experience a slow-moving motion with driving fields below the ...

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
