Materials Nexus, in collaboration with the University of Sheffield, has utilized AI to develop a new rare-earth-free permanent magnet named MagNex. This AI-driven discovery process was 200 times faster than traditional manual methods, offering hope for meeting the increasing demand for powerful magnets in various industries, especially in electric vehicles. The move towards electric mobility has raised the need for compact, high-power motors, with permanent magnet motors being the preferred choice. The current reliance on rare earth materials like neodymium and dysprosium for these magnets poses environmental and supply chain challenges. MagNex, synthesized and tested within three months, offers a promising alternative with reduced material costs and carbon emissions. Materials Nexus aims to accelerate the discovery of sustainable materials using AI, catering to various industries beyond magnetism. The development of MagNex showcases the potential of AI in revolutionizing material discovery processes for future technologies.

The existence of the iron nitride magnets as a REE-free (rare-earth-element-free) alternative to the REE magnets has been perfectly known for many years, much more than a decade. So no new magnetic material has been discovered by the AI, unless it differs somehow in some small details from the known iron nitride magnets.
Such magnets have been patented many years ago and startups have been created with the purpose of making and selling such magnets.
Nevertheless, until now there have been no practical results, for reasons that are kept secret by those who attempt to develop such magnets, but it appears that the crystal structure with good magnetic properties is unstable, so either the yields for making such magnets are very poor or the magnets degrade in time very quickly.
Computer-enhanced chemical and biological compound theory space search has been an idea for a while, so is it "working" now? How?
Looks a bit like "New battery will replace lithium" articles
At the speed of man.
