Direct observation of nanoscale pinning centers in Ce(Co0.8Cu0.2)5.4 permanent magnets
Nikita Polin, Shangbin Shen, Fernando Maccari +15
Permanent magnets containing rare earth elements are essential components for the electrification of society. Ce(Co1-xCux)5 permanent magnets are a model system known for their sub…
Effect of Ag nano-additivation on microstructure formation in Nd-Fe-B magnets built by laser powder bed fusion
Varatharaja Nallathambi, Philipp Gabriel, Xinren Chen +6
Laser powder bed fusion (PBF-LB/M) enables the near-net shape production of permanent magnets with complex geometry while reducing material waste. However, controlling the microstr…
Formation of cellular/lamellar nanostructure in SmCo-type binary and ternary Sm-Co-Zr magnets
Nikita Polin, Konstantin P. Skokov, Alex Aubert +6
2:17 SmCo magnets with a quinary composition of Sm(Co,Cu,Fe,Zr) are industrially relevant hard magnets used in high temperature and corrosive environments. Their complex c…
Understanding High Coercivity in ThMn12-Type Sm-Zr-Fe-Co-Ti Permanent Magnet Powders through Nanoscale Analysis
Nikita Polin, Alexander M. Gabay, Chaoya Han +6
ThMn12-type (Sm,Zr)1(Fe,Co,Ti)12 compounds show great potential for permanent magnets. Magnetically hard anisotropic powders prepared via reduction-diffusion exhibit a significant…
