Ferromagnetism

Definition

Ferromagnetism is a form of magnetic ordering in which the intrinsic magnetic dipole moment, or spin, of electrons on each crystal-lattice site all align in the same direction. It is the phenomenon that gives materials such as iron, cobalt and nickel their magnetic properties.

    Introduced originally to mimic the unusual, frustrated behaviour of spin ice pyrochlores, artificial spin ice can be realized in odd, dedicated geometries that open the door to new manifestations of a higher level of frustration.

    Molecular layers show antiferromagnetic ordering up to room temperature and are able to exchange bias a ferromagnetic electrode, demonstrating that molecules could be much more than a simple vehicle for transporting spin.

    Exchange bias is a magnetic phenomenon that has facilitated the ever-increasing storage density of magnetic recording systems. The finding of high tunable exchange bias in certain Heusler alloys indicates new routes for the design of rare-earth-free hard magnetic materials.
