Chiral Magnetism and Organic Magnets.

Non collinear magnets in which non collinearity is due to DM interaction or to magnetic frustration. We also focus our attention to the new properties emerging from the quantum nature of the spin in purely organic magnets.

About Our Research Group

M4 is a multidisciplinary research group formed by physicist (theoreticians and experimentalist), chemists, engineers and biologists from the Spanish National Research Council (CSIC) or the University of Zaragoza and belonging to several Aragonese Institutes (INMA, ISQCH) 

The main research lines are four; chiral magnetism and organic magnets, manometric platforms for biomedicine, synthesis and structural characterization of molecular magnets, and magneto-caloric materials.  All the research subjects of the group have as common points the multi functionality and the molecular character of the materials of interest.

The group uses the organometallic routes for synthesising materials.  The main experimental techniques employed by the group are magnetometry, calorimetry and Xray diffraction.  The group has also a vast experience in the use of large scale research facilities, like neutron sources and synchrotrons.

Advanced Scientific Instrumentation

The group has an long standing tradition in the development of scientific instrumentation for neutron sources (neutron detectors, instruments, simulations, etc...) and calorimetry techniques.
Also the group is the responsible for the management of the Spanish CRGs instruments at the Institut Laue Langevin (ILL)
