Finite-size effects in fine particles: magnetic and transport properties
Xavier Batlle,Amílcar Labarta +1 more
TL;DR: In this article, a review of the most relevant finite-size and surface effects in the magnetic and transport properties of magnetic fine particles and granular solids is presented, where the stability of the particle magnetization, superparamagnetic regime and the magnetic relaxation are discussed.
Journal ArticleDOI
Nanoparticle-mediated local and remote manipulation of protein aggregation
Marcelo J. Kogan,Neus G. Bastús,Roger Amigo,Dolors Grillo-Bosch,Eyleen Araya,Antonio Turiel,Amílcar Labarta,Ernest Giralt,Víctor F. Puntes +8 more
TL;DR: Simultaneous tagging and manipulation by AuNP of Abeta at different stages of aggregation allow both, noninvasive exploration and dissolution of molecular aggregates.
Journal ArticleDOI
Surfactant effects in magnetite nanoparticles of controlled size
Pablo Guardia,B. Batlle-Brugal,Alejandro G. Roca,Òscar Iglesias,María del Puerto Morales,Carlos J. Serna,Amílcar Labarta,Xavier Batlle +7 more
TL;DR: In this article, the authors showed that the oleic acid molecules covalently bonded to the nanoparticle surface yield a strong reduction in the surface spin disorder, in contrast to results in small particle systems for which magnetite is usually much smaller.
Journal ArticleDOI
Exchange bias phenomenology and models of core/shell nanoparticles.
TL;DR: In this paper, the authors present results of simulations based on a simple model of a core/shell nanoparticle in which the values of microscopic parameters such as anisotropy and exchange constants can be tuned in the core, shell and at the interfacial regions, offering new insight on the microscopic origin of the experimental phenomenology.
Journal ArticleDOI
Tuning the Size, the Shape, and the Magnetic Properties of Iron Oxide Nanoparticles
TL;DR: In this paper, the role of both the surfactant and reducing agent on the shape, the size distribution, and the magnetic properties of iron oxide nanoparticles was investigated. But the authors focused on synthesizing magnetic nanoparticles with high crystal quality and good magnetic response.
