US Patent 8093669 - Magnetic nanotransistor


This patent from Honda Motor teaches a new type of nanotransistor based on switching the magnetic moment of a particle attached to a carbon nanotube. Claim 1 reads:

1. A magnetic nanotransistor, comprising:

a first magnetizable electrode;

a second magnetizable electrode; and

at least one nanotube arranged between the first magnetizable electrode and the second magnetizable electrode wherein the nanotube has at least one magnetic particle attached thereto and wherein the magnetic moment of the particle is capable of being reversed by application of an external magnetic field.
