The New Horizons on Nanostructured Magnetic Materials (H-MAG) workshop series, sponsored by the Nanostructured Magnetic Materials Laboratory (nM2-Lab) promises to be a dynamic biannual event set to explore and advance the field of nanostructured magnetic materials. Each year, the workshop will focus on a different cutting-edge topic, attracting academic scientists, researchers, and industry professionals to share their experiences and the latest achievements and challenges in modeling, fabrication, and characterization of nanostructured magnetic materials, devices, and systems. The H-MAG workshop aspires to become a hallmark in the field of nanostructured magnetic materials. The Workshop will be hosted in Iglesias, a historical city in the south-western corner of Sardegna (Italy), rich in cultural attractions, centuries-old traditions and natural beauties punctuating the territory.
