Rare earth elements have long been the backbone of high-tech magnets, with metals like neodymium and dysprosium playing pivotal roles in various industries. However, the scarcity and rising demand for these valuable resources have prompted researchers to seek alternative solutions. In an effort to reduce our reliance on rare earth magnets, scientists are exploring innovative materials and alloy combinations. Among the promising contenders is cerium, an abundant and accessible rare earth element, showing potential to replace or augment neodymium magnets. In this article, we’ll delve into the groundbreaking research by Thomas Lograsso and his team at the Ames Laboratory of the US Department of Energy.

Rare earth elements, often shrouded in mystery, play a crucial role in our modern world. From smartphones to electric vehicles, renewable energy technologies, and even defense systems, these elements are the unsung heroes that make our daily lives more sustainable, efficient, and connected. In this article, we’ll delve into the fascinating world of rare earth elements, with a focus on the versatile element, neodymium.

Rare earth elements (REEs) are a group of seventeen chemical elements that occupy the lanthanide series of the periodic table, along with scandium and yttrium. Despite the name, they are not necessarily rare, but they are typically found in low concentrations, making their extraction and purification challenging and costly.
