The electron transport properties of B80 fullerene are studied using first-principles density functional theory in conjunction with the Landauer-Buettiker quantum transport formalism. The electron transmission in B80 fullerene is calculated to be much higher than that in C60 fullerene in the Fermi-level region. The enhanced transmission in the B80 fullerene is attributed to its spatially extended charge distribution in delocalized bonds.
We present here the results of theoretical calculations on the spin-valve effect in a Ni-C60-Ni device. The magnitude of the junction magnetoresistance (JMR) is found to be significantly large for the device, which makes it a promising candidate for realistic applications in molecular spintronics. The exploration of the origin of the observed spin-valve effect in the Ni-C60-Ni system will be discussed.
