Permanent magnets (PM) are critical components for electric motors and power generators.
Key properties of permanent magnets, especially coercivity and remanent magnetization …

Manganese-based permanent magnetic materials have become an area of significant
research activity in recent years as a potential alternative to permanent magnets based on …

Defects of various kinds strongly affect local magnetic anisotropy and thus play a crucial role
in coercivity in high-performance permanent magnets. In particular, in rare-earth-free …

Permanent magnets are fundamental constituents in key sectors such as energy and
transport, but also robotics, automatization, medicine, etc. High-performance magnets are …

The main goal of this work is the adoption of additive manufacturing for the production of
inexpensive rare-earth free MnAl-based permanent magnets. The use of more advanced …

The low cost, rare earth free τ-phase of MnAl has high potential to partially replace bonded
Nd2Fe14B rare earth permanent magnets. However, the τ-phase is metastable and it is …

MnAl alloys are considered to be an important candidate to plug the gap between Nd-Fe-B
magnets and ferrites, and their microstructure is closely related with the magnetic properties …

In this chapter, we are presenting the developments in permanent magnetic materials and
their processing techniques. We discuss different alloy systems, rare-earth (RE) Nd-Fe-B …

Isotropic nanocrystalline MnAlC particles with quasi-spherical shape were synthesized by
gas-atomization being afterwards milled for a short time of 60 s. Gas-atomized and milled …

The phase transformation in two modes, including both displacive and massive growth of τ-
phase from ε-MnAl (C), was observed by in situ transmission electron microscopy. The exact …
