The return of the spin echo – EurekAlert
The spin of particles can be manipulated by a magnetic field. This principle is the basic idea behind magnetic resonance imaging as used in hospitals. A surprising effect has now been discovered in the spins of phosphorus atoms coupled to microwaves: If the a…

IMAGE: If the spins of phosphorus atoms in silicon are cleverly excited with microwave pulses, a so-called spin echo signal can be detected after a certain time. Surprisingly, this spin echo…

Small particles can have an angular momentum that points in a certain direction – the spin. This spin can be manipulated by a magnetic field. This principle, for example, is the basic idea behind magnetic resonance imaging as used in hospitals. An international res…
