Periodic atom chains of carbon-cobalt compounds,
(CnCo)
, comprise both conducting and insulating
electronic properties simultaneously depending on the spin type of
electrons, and hence are half-metals. Their band gap and the net
magnetic moment oscillate with the number of carbon atoms in a
unit cell. Finite segments of these chains also show interesting
magnetic and transport properties. When connected to appropriate
metallic electrodes the antiferromagnetic CoCnCo segments
behave like molecular spin-valves, which can be conveniently
manipulated.
