Like refrigerator magnets, chromium triiodide is a ferromagnet, a material that
generates a permanent magnetic field owing to the aligned
spins of its
electrons.
In ordinary magnets, both individual
electron spins and the motion of
electrons in their atomic orbitals
generate magnetic fields.
Researchers in Spain have discovered that if lead atoms are intercalated on a graphene sheet, a powerful magnetic field is
generated by the interaction of the
electrons»
spin with their orbital movement.
Consequently, the analysis revealed that the metal atoms at the center of the organic molecules retained
electron spins, which could
generate magnetism.
While electronics depends on the charge of
electrons to
generate the binary ones or zeroes of computer data, spintronics depends on the property of
electrons called
spin.
For the
spin - Hall effect
electron -
spins are
generated by irradiating the sample with circularly polarised light.
Electrons have two fundamental properties, charge and
spin,
generating such phenomena as electricity, magnetism, thermal conductivity, and superconductivity in materials.
Now, imagine that on the other side of your light switch, one of two scenarios exists: the first is a «clean» world where wind turbines
spin to
generate electrons to power your light bulb and the other is a «dirty» world where a coal - fired power plant lumbers into operation, spewing carbon dioxide (CO2) and other pollutants into the atmosphere, to create the same level of brightness in your living room.
