A new experimental scheme allows the controlled generation and observation of magnetic avalanches, a cascade of spin flips that propagates through a magnetic sample like a three-dimensional fire.

Experiments demonstrate the possibility of engineering stable, nanometer-scale magnetic structures in thin magnetic films by firing laser pulses at them.

In some transition metal oxides, disorder makes  the dielectric constant highly sensitive to an applied magnetic field over a broad range of temperatures.

Helicoidal magnetic order induces a record high electrical polarization.

Ferroelectric domain patterns enable voltage-induced magnetization reversal in a magnetic alloy.

Electromagnons open up new opportunities to control electric and magnetic properties.

A strontium-based metal oxide with radioactive technetium exhibits the highest antiferromagnetic ordering temperature in a material without a third-row transition metal.

Experiments show that it may be possible to achieve control of magnetization by an external electric field in a material by altering the balance between competing physical processes.

The magnetic state of a multiferroic device can be controlled purely by an electric field—a property that could greatly reduce overheating in data storage devices.

Structurally soft materials—like shape memory alloys—are well suited to making epitaxial films.

A new porous material changes shape in response to a magnetic field and could be lighter and cheaper than others on the market.

A theory proposes a new way in which a material could allow magnetic and electric fields to influence one another–a property with great potential for new devices.
