The NanoMag project is to improve and redefine existing analyzing methods and in some cases, to develop new analyzing methods for magnetic nanostructures. Using improved manufacturing technologies we will synthesize magnetic nanoparticles with specific properties that will be analyzed with a multitude of characterization techniques (focusing on both structural as well as magnetic properties) and bring the experimental results together to obtain a self-consistent picture which describes how structural and magnetic properties are interrelated. This extensive survey will be used to define standard measurements and techniques which are necessary for defining a magnetic nanostructure and quality control. NanoMag brings together Europe’s and internationally leading experts in; manufacturing of magnetic single-core nanoparticles and magnetic multi-core particles, analyzing and characterization of magnetic nanostructures and national metrology institutes. In the consortium we have gathered partners within research institutes, universities and metrology institutes, all carrying out front end research and developing applications in the field of magnetic nanoparticles.
