Triggering of spin-flipping-modulated exchange bias in FeCo nanoparticles by electronic excitation
The exchange coupling between ferromagnetic (FM)-antiferromagnetic (AF) interfaces is a key element of modern spintronic devices. We here introduce a new way of triggering exchange bias (EB) in swift heavy ion (SHI) irradiated FeCo-SiO2 films, which is a manifestation of spin-flipping at high irradiation fluence. The elongation of FeCo nanoparticles (NPs) in SiO2 matrix gives rise to perpendicu...
متن کاملModelling exchange bias in core/shell nanoparticles.
We present an atomistic model of a single nanoparticle with core/shell structure that takes into account its lattice structure and spherical geometry, and in which the values of microscopic parameters such as anisotropy and exchange constants can be tuned in the core, shell and interfacial regions. By means of Monte Carlo simulations of the hysteresis loops based on this model, we have determin...
متن کاملSynthesis and stabilization of FeCo nanoparticles.
FeCo alloys are an important soft magnetic material because of their unique magnetic properties including large permeability and very high saturation magnetization. FeCo nanoparticles are ideal building blocks for nanostructured thin film or bulk magnetic materials1-3 and are also suitable for biomedical applications.4 However, synthesis of monodisperse FeCo nanoparticles remains a challenging ...
متن کاملExchange bias effect in Au-Fe3O4 nanocomposites.
We report exchange bias (EB) effect in the Au-Fe3O4 composite nanoparticle system, where one or more Fe3O4 nanoparticles are attached to an Au seed particle forming 'dimer' and 'cluster' morphologies, with the clusters showing much stronger EB in comparison with the dimers. The EB effect develops due to the presence of stress at the Au-Fe3O4 interface which leads to the generation of highly dis...
متن کاملPhenomenology and Models of Exchange Bias in Core/shell Nanoparticles
Magnetic nanomaterials present new magnetic and transport properties that arise due to a complex interplay between the intrinsic properties of the constituents (such as specifically tailored microstructure and finite size or surface effects) and the interactions among the entities forming them [1]. When reducing the size of magnetic particles to the nanoscale, surface and finite-size effects be...
