National Institute of Standards and Technology scientists have demonstrated a tiny sensor that can detect magnetic field changes as small as 70 femtoteslas (a level that is equivalent to the brain ...

Magnetic sensors are implemented in all kinds of mechanical and electronic mechanisms, including automobiles. When implemented in the steering system, they can detect if and when a vehicle is in ...

The research on magnetic multilayers in the 1980s 1 has led to a new type of electronics exploiting the spin of the carriers, so-called spintronics 2. Simultaneously, advances in ferroelectric ...
