This project aims to discover new magnetic materials that are competitive for advanced technology applications, free of the rare earth metals that currently dominate the high-performance end of the market. Global demand for non-renewable rare earth metals is rapidly approaching a critical point and alternatives are needed. The project will use data-mining algorithms augmented by quantum calculations to find the most promising candidates among tens of thousands of reported but untested materials, so that synthesis and characterisation resources can be directed to the right places. After iterative cycling to optimise the chemical composition and structure, the best materials will be prepared for fabrication into technologically useful forms.

该项目旨在发现新的磁性材料，这些材料在先进技术应用中具有竞争力，不含目前主导高性能市场的稀土金属。全球对不可再生稀土金属的需求正迅速接近临界点，需要替代品。该项目将使用量子计算增强的数据挖掘算法，在数万种已报道但未经测试的材料中找到最有希望的候选材料，以便将合成和表征资源引导到正确的地方。经过反复循环以优化化学成分和结构，最好的材料将被制备成技术上有用的形式。
