Useful for spintronics: Big surprises in a thin surface region
Useful for spintronics: Big surprises in a thin surface region
The need for ever faster and more efficient electronic devices is growing rapidly, and thus the demand for new materials with new properties. Oxides, especially ones based on strontium titanate (SrTiO 3 ), play an important role here. Researchers recently discovered that SrTiO 3 , although actually an insulator, can form a metallic layer on its surface, in which electric current can flow.

Observed live with x-ray laser: electricity controls magnetism
Observed live with x-ray laser: electricity controls magnetism
Data on a hard drive is stored by flipping small magnetic domains. Researchers have now changed the magnetic arrangement in a material much faster than is possible with today's hard drives. The researchers used a new technique where an electric field triggers these changes, in contrast to the magnetic fields commonly used in consumer devices.
