But physicists are now fashioning a new parallel system called spintronics — of which skyrmions are a part — based on
the motion of electron spin, that property that makes atoms magnetic (SN Online: 9/26/17).
At room temperature
the motions of electron spins can be largely affected by heat.
Not exact matches
In ordinary magnets, both individual
electron spins and the
motion of electrons in their atomic orbitals generate magnetic fields.
The material
of their choice, the compound Ag2BiO3, is exceptional for two reasons; on the one hand it is composed
of the heavy element bismuth, which allows the
spin of the
electron to interact with its own
motion (
spin - orbit coupling)-- a feature that has no analogy in classical physics.
After overcoming a few technical hurdles related to this circular
motion, they tracked

spin precession over the course
of 0.7 seconds — about 1000 times longer than was previously possible with beams, which should open the way to greater sensitivity.
One might think these two instruments have nothing in common, but they do: both technologies are based on precise measurement the
spin of the atom, the gyroscope - like
motion of the
electrons and the nucleus.
The cooling slowed the natural
motion of the atoms to a near stop, which allowed the researchers to observe the
electron spins» dance around the Ytterbium (Yb) atoms in the YbMgGaO4 crystal.
