Seminar DCMI : Jose A. De Toro

"Inter- and intra-particle interactions in assemblies of magnetic nanoparticles"

Jose A. De Toro (Applied Physics Department & IRICA
Universidad de Castilla-La Mancha
)

In this talk I will summarize some results obtained at UCLM’s Applied Nanomagnetism Group (https://blog.uclm.es/apnano/) dealing with magnetic nanoparticles (NPs) prepared both by chemical methods (Fe oxide-based NPs) and by high-vacuum gas-phase aggregation (metallic NPs). These include the demonstration of a benchmark superspin glass (a replica of the spin-glass state driven by dipolar interactions), the effects of surface spin disorder and exchange bias in the magnetic stability of the NPs, the preparation of NP nanostripes, and the proposal of a novel “supermagnetostriction” effect in self-assemblies of nanocubes.
