Query: Exchange bias phenomenology and models of core/shell nanoparticles   Some of the main experimental observations related to the occurrence of
exchange bias in magnetic systems are reviewed, focusing the attention on the
peculiar phenomenology associated to nanoparticles with core/shell structure as
compared to thin film bilayers. The main open questions posed by the
experimental observations are presented and contrasted to existing theories and
models for exchange bias formulated up to date. We also 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. A detailed
study of the of the magnetic order of the interfacial spins shows compelling
evidence that most of the experimentally observed effects can be qualitatively
accounted within the context of this model and allows also to quantify the
magnitude of the loop shifts with striking agreement with the macroscopic
observed values.
