Unlike other concepts that harness electrons, spin
current can transfer information without causing heat from the electric charge, which is a serious problem for current semiconductor devices.
The most common method for polarising nuclear spin
is called dynamic nuclear polarisation; this means that the electrons' spin
simply influences the nucleus to spin
in the same direction.
Second, measuring black hole spin
can tell us about the recent growth history of a SMBH and its host galaxy.
The researchers found that electrons in the new system had stable spins
for up to a nanosecond or so.
For the vertically oriented neutron spin
in a simultaneous measurement of R and N one of the correlations will produce an up-down asymmetry while the other leads to a forward-backward asymmetry.
Pierre Luc Gagnon: McTwists if you flip it, and fives if you spin
Using 8-hydroxyquinoline aluminum (Alq3), the scientists sandwiched the organic semiconductor between two metallic layers--one consisting of lanthanum strontium manganese oxide, the other of cobalt--to build three-layer organic spin
"Our experiments removed this magnetic interaction and looked to see if there might be some other interaction that would orient our experimental spins
. One interpretation of this 'other' interaction is that it could be a long-range interaction between the spins
in our apparatus, and the electron spins
within the Earth, that have been aligned by the geomagnetic field.
Here I is spin
of a nucleus, [p.sub.t] is polarization of a target, s is a neutron spin
, and k is its wave vector.
This is called "spin
current" and unlike other concepts of harnessing electrons, the spin
current can transfer information without generating heat in electric devices.
can be bad because in some cases of wing and fuselage loading and distribution of mass, recovery is impossible through normal means.
Scientists have long wondered whether superfluidity in a fermionic fluid could persist in the face of a spin
imbalance, when there are more fermions with one spin
than with the other.
are rotated by [pi]/2 from the longitudinal to transverse direction in the first [pi]/2 coil.
A perhaps greater challenge will be to divide the electron spins
more efficiently - in the present study, only a few of every hundred electrons separated according to their spin
The phrase is often a catchall, including encounters with inadvertent stalls and spins
, wake turbulence, and uncommanded spirals.
