Specimen preparation for atom probe tomography analysis of complex multifunctional nanoparticles and nanostructures: state-of-the-art and challenges
Varatharaja Nallathambi, Se-Ho Kim, Nikita Polin +4
Atom probe tomography (APT) provides the three-dimensional composition of materials at near-atomic length scales, achieving detection limits in the range of tens of atomic parts-pe…
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…
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 ce…
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…
A machine learning framework for quantifying chemical segregation and microstructural features in atom probe tomography data
Alaukik Saxena, Nikita Polin, Navyanth Kusampudi +7
Atom probe tomography (APT) is ideally suited to characterize and understand the interplay of chemical segregation and microstructure in modern multicomponent materials. Yet, the q…
Identifying grain boundary and intragranular pinning centres in Sm2(Co,Fe,Cu,Zr)17 permanent magnets to guide performance optimisation
Stefan Giron, Nikita Polin, Esmaeil Adabifiroozjaei +21
Permanent magnets draw their properties from a complex interplay of chemical composition and phase, each with their associated intrinsic magnetic properties. Gaining an understandi…
