New Exchange-Coupled Manganese-Based Magnetic Materials

NEXMAG is a collaborative research project funded by MINECO, the Research Council of Norway and the Slovak Academy of Sciences in the framework of the M-era.Net consortium. It officially started in December 2015 and it will run for three years until the end of 2018. NEXMAG is coordinated by Dr Alberto Bollero at IMDEA Nanociencia.


Magnetic materials are important in the production, transmission and use of electrical energy. An increased use of low carbon technologies is necessary to ensure a high living standard. Permanent magnets (PMs), used in a multitude of technological applications, play a very important role in these efforts. However, these PMs contain critical raw materials [rare-earths (REs)] as fundamental constituents and EU does not own the natural resources.

The Project

NEXMAG project considers as main objective the development of nanocomposite Manganese-based materials that will result in (BH)max=4.5-15 MGOe through an efficient coupling between two complementary phases:

  1. Magnetically hard phases (large anisotropy): MnAl; MnBi.
  2. Magnetically soft phases (high saturation magnetisation): metals (Fe, FeCo).

These new magnets - constituted by non-critical elements - will allow substitution of RE-PMs in many technological applications therefore contributing to solve the EU dependency of REs.

The Consortium

The NEXMAG consortium combines complementary expertise within materials synthesis, processing and characterization. It consists of three partner institutions:

Advisory Board

The scientific and technological impacts of NEXMAG are manifested by participation of a long time experienced PMs-enterprise (IMA S.L.) in addition to a prominent research group in the field of new permanent magnets (Chemical Engineering Department at Northeastern University in Boston) as Members of the Advisory Board.
