Magnetic behavior of nanoparticle assemblies: our work in a new Scientific Reports paper

Editor — Thu, 14 Feb 2013 13:22:32 +0000

Thanks to an international collaboration carried out by Dr. Miriam Varón during her doctoral work, our group has recently published the paper “Dipolar Magnetism in Ordered and Disordered Low-Dimensional Nanoparticle Assemblies” in Scientific Reports. The work was led by Prof. Dr. Cathrine Frandsen from the Technical University of Denmark.

The paper presents the results on the use of electron holography to study 1D and 2D self-assemblies of magnetic (Cobalt) nanoparticles. The work reveals the correlation between particle arrangement and magnetic order, leading to the conclusion that ferromagnetism exists in these structures even in the absence of underlying crystallinity. This contributes not only to elucidating mechanisms at the nanoscale, but also to the application of nanoparticle assemblies in magnetic devices such as memories and sensors.

Miriam Varón has successfully defended her PhD thesis entitled “Synthesis of Nanoparticles and Nanostructured Materials by Self-Assembly”, last Thursday May 31.

The PhD Committee was formed by Prof. Cathrine Frandsen (Technical University of Denmark), Dra. Maria del Puerto Morales Herrero (Instituto de Ciencia de Materiales de Madrid, Spain) and Dr. Andreu Cabot (Catalonia Institute for Energy Research, Spain).

Congratulations, Miriam!!!
