Abstract

Nanoclusters, aggregates of a few tens to millions of atoms or molecules, have been extensively studied over the past decades. Core–shell nanoclusters have received increasing attention because of their tunable physical and chemical properties through controlling chemical composition and relative sizes of core and shell. The magnetic core–shell nanoclusters are of particular interests because these heterogeneous nanostructures offer opportunities for developing devices and cluster-assembled materials with new functions for magnetic recording, bio, and medical applications.

The purpose of this review is to report latest progress in the experimental and theoretical studies of bimetallic magnetic core–shell nanoclusters (e.g., at least one component of the constitution is magnetic). Due to page limit, a concise survey of synthetic techniques and main experimental characterizations for magnetic properties is presented. A more detailed overview is given to previous theoretical work.
