Conferencia ICMA: "Itinerant magnets: A physicist’s toy in chemist's hands".- Jueves 3 de noviembre
El Profesor Michael Shatruk del Department of Chemistry & Biochemistry de la Florida State University ofrecerá el próximo 3 de noviembre la conferencia titulada: “ITINERANT MAGNETS:A PHYSICIST’S TOY IN CHEMIST’S HANDS”La conferencia tendrá lugar el próximo jueves 3 de noviembre a las 12:00 horas en la Sala de grados de la Facultad de Ciencias de la Universidad de Zaragoza
Resumen:
Exploration of chemical factors that influence magnetic properties of solids is one of the major steps in the preparation of novel magnetic materials. The search for new magnets with improved performance requires fundamental understanding of correlations between the crystal, electronic, and magnetic structures of existing materials, as well as innovative synthetic approaches that target the discovery of new magnets. This talk will focus on three topics:
1. Control of magnetic phase transitions in itinerant magnets by modification of the electronic band structure. We will demonstrate a unified action of physical pressure, chemical compression, and aliovalent substitution on the magnetic behavior of rare-earth cobalt pnictides, RCo2Pn2 (Pn = P, As).
2. Magnetocaloric effect and application of itinerant magnets in magnetic refrigeration. In particular,we will consider layered-structure boride materials, such as AlFe2B2, for which we have recently discovered a large magnetocaloric effect at room temperature.
3. Microwave synthesis of hybrid nanostructured magnets with enhanced energy products. A combination of hard and soft magnetic materials at the nanoscale allows us to observe an evolution of magnetic exchange regimes and to demonstrate experimentally the exchange-springbehavior in hybrid nanomagnets.
