Researchers at TU Darmstadt have found a recipe for producing soft magnets that are more robust than those previously used.

Soft magnetic materials are used, among other things, for generators in wind and hydroelectric power plants, so they are of great importance for the energy transition.

However, the materials commonly used up to now wear out quickly under load.

Together with colleagues from the Max Planck Institute for Iron Research and the Chinese Central South University, the Darmstadt scientists have developed the idea for a new multi-component alloy.

It contains iron, nickel, cobalt, tantalum and aluminum.

This mixture is intended to give soft magnets greater malleability and strength without the magnetic properties suffering as a result.

With the help of computer simulations and machine learning, the researchers now want to try to reduce the cost of the new alloy.

This is possible if the amount of expensive elements such as cobalt can be reduced or if such elements can be replaced by others with similar properties.

According to the TU, the combination found can serve as a model for other multi-component alloys.

Other new materials with unusual properties could be produced using this pattern.

Here is the study.
