On the essential spectrum of the Laplacian and vague convergence of the curvature at infinity
Hironori Kumura
We shall prove that under some volume growth condition, the essential spectrum of the Laplacian contains the interval if an -dimensional Riemannian manifo…
Spin dependent transport of ``nonmagnetic metal/zigzag nanotube encapsulating magnetic atoms/nonmagnetic metal'' junctions
Satoshi Kokado, Kikuo Harigaya
Towards a novel magnetoresistance (MR) device with a carbon nanotube, we propose ``nonmagnetic metal/zigzag nanotube encapsulating magnetic atoms/nonmagnetic metal'' junctions. We…
A Theoretical Study on Spin-Dependent Transport of "Ferromagnet/Carbon Nanotube Encapsulating Magnetic Atoms/Ferromagnet" Junctions with 4-Valued Conductances
Satoshi Kokado, Kikuo Harigaya
As a novel function of ferromagnet (FM)/spacer/FM junctions, we theoretically investigate multiple-valued (or multi-level) cell property, which is in principle realized by sensing…
Large positive magnetic susceptibility of nanotube torus
Ryo Tamura, Mitsuhiro Ikuta, Toru Hirahara +1
We calculate the magnetic moment caused by the persistent currents in polygonal carbon nanotube tori by the tight binding model. The polygonal CNT tori are formed by introducing he…
