Domain Structure Transformation and Impedance Tuning in Partially Nanocrystallized Fe-Based Microwires [PDF]

Sensors
Fe-based amorphous microwires were studied to examine the effect of partial surface nanocrystallization on their magnetic and electrical properties. Controlled annealing was used to induce nanocrystallization within the surface layer of the metallic core.

Sparse Nanocrystals Enable Ultra-Low Coercivity and Remarkable Mechanical Robustness in High-Entropy Amorphous Alloy. [PDF]

Adv Sci (Weinh)
An order modulation strategy is introduced to overcome trade‐off between mechanical and magnetic properties by constructing an amorphous‐nanocrystalline transitional structure in a ferromagnetic HEA system. This enable the resultant alloys to combine an ultra‐low coercivity of 0.3 A m−1 with a remarkable mechanical toughness, thereby achieving a ...
