Neutrons help demystify multiferroic materials

Materials used in electronic devices are typically chosen because they possess either special magnetic or special electrical properties. However, an international team of researchers using neutron scattering recently identified ...

Sensor the size of a nitrogen atom investigates hard drives

Integrated circuitry is becoming increasingly complex. These days a Pentium processor contains some 30 million transistors. And the magnetic structures found in hard drives measure just 10 to 20 nanometers across – less ...

Spinning diamonds for quantum precision

We live in a noisy world. Interference from light, vibrations, electromagnetic radiation and sound can be annoying; it messes with our sleep and can interfere with our electrical equipment.

Boosting the ability to detect superweak magnetic fields

Each beat of your heart or burst of brain activity relies on tiny electrophysiological currents that generate minuscule ripples in the surrounding magnetic field. These field variations provide the basis for a range of research ...

Controlling the stiffness of a material at the nanoscale

Using a needle far thinner than a human hair, scientists revealed how to control mechanical stiffness in a promising material. The team applied an electric field with a nano-sized needle to cause a reversible change in the ...
