New White Paper from Arnold Magnetics: Magnetization Losses in Rare Earth Permanent Magnets

May 30, 2023 Editorial Staff Comments Off on New White Paper from Arnold Magnetics: Magnetization Losses in Rare Earth Permanent Magnets

This White Paper from Arnold Magnetics describes the magnetization losses that are possible in SmCo and NdFeB permanent magnet materials. Reversible losses are first discussed followed by irreversible losses, which can be caused by temperature, external fields or radiation. Losses over time by magnetic viscosity are also discussed. Finally, permanent losses caused by corrosion, hydrogen, high temperatures and radiation are considered.

Neo Performance Materials: Names New President; Acquires SG Technologies in UK, and Rare Earths Exploration License in Greenland 

May 15, 2023 Editorial Staff Comments Off on Neo Performance Materials: Names New President; Acquires SG Technologies in UK, and Rare Earths Exploration License in Greenland 

Neo Performance Materials, considered a bellwether of the permanent magnetics industry, has named a new president in concert with the upcoming retirement of its CEO and long-time leader Constantine Karayannopoulos and, in rapid succession, recently consummated two deals that further its mines-to-magnets vertical integration strategy:

By acquiring SG Technologies Group Ltd (SGTec) in the UK, Neo moved further up the value chain and expands its specialty manufacturing footprint in Europe to better serve rapidly growing magnet demand from the electric vehicles, electronics and clean energy industries.

In Greenland, it progressed another step in developing its own rare earths mine as the government approved transfer of an exploration license from Hudson Resources of Canada, clearing the way for Neo to acquire it. […]
