Understanding the Shift in Magnet Technology

As the global demand for renewable energy sources surges, particularly in wind power and electric vehicles, the reliance on neodymium magnets has intensified. These magnets, crucial for high-performance motors, are facing potential supply vulnerabilities due to the scarcity of rare earth elements like dysprosium and terbium. In this scenario, the development of alternative materials to complement or replace neodymium magnets has become increasingly critical. This article delves into the upcoming seminar that will discuss the latest advancements in post-neodymium magnet technology, particularly focusing on Sm-Fe-N magnets.

Seminar Outline

The seminar titled “Latest Trends in Post-Neodymium Magnet Development: Insights on Sm-Fe-N Technologies” is scheduled for June 17, 2026, from 1:30 PM to 3:30 PM JST, featuring an online format via Zoom. It will be conducted by Dr. Akihide Hosokawa, a leading researcher at the National Institute of Advanced Industrial Science and Technology. The participation fee is set at 29,700 yen (tax included).

Purpose and Content

During the seminar, participants will gain insights into the fundamental principles of permanent magnets, including their characteristics and manufacturing processes. An overview of the entire landscape of post-neodymium magnet candidates will be provided, emphasizing the burgeoning focus on Sm-Fe-N (Sm2Fe17N3) magnets.

Historical Context and Advancements

The seminar will begin by exploring the commercial history of Sm-Fe-N magnets from 1990 to 2015, highlighting the challenges associated with sintering and the advent of electric-pressure sintering processes. Subsequent sections will focus on the difficulties posed by oxidation, the low-oxygen powder metallurgy breakthrough introduced in 2015, and ongoing challenges.

Innovations in Magnet Enhancement

Additionally, discussions will cover advancements in refining techniques such as cold plastic deformation to improve magnet density, alongside recent endeavors in liquid-phase sintering techniques and their associated challenges. Participants will also learn about cutting-edge research aimed at enhancing magnet performance further through the development of iron-rich Sm-Fe-N magnets and nano-composite magnets.

Target Audience

This seminar is designed for professionals involved in magnet material technology, process design, and for those leading technical teams. Motor technology engineers and designers, along with individuals looking to engage in magnet material development, will also find the content immensely beneficial.

Conclusion

The urgency for alternatives to neodymium magnets stems not only from looming supply risks but also from the broader push for sustainable energy solutions. By attending this seminar, industry professionals can better prepare for the shift in magnet technology and its applications, thus ensuring they stay ahead in this rapidly evolving sector. The discussions will illuminate the pathway towards more resilient and efficient magnet materials to address future energy demands.
