Quantum magnetic disk

چکیده
A quantum magnetic disk (QMD) a new paradigm for magnetic recording is proposed and fabricated. Tile QMD consists of pre-fabricated single-domain magnetic structures that have an identical shape and are uniformly embedded in a nonmagnetic disk. Each single-domain structure has a quantized magnetic moment and can store one bit of information. The QMD has a number of advantages over the conventional disk and is suitable for ultra-high density recording. Two processes based on electron beam nanolithography and other nanofabrication technologies have been developed to fabricate QMDs. QMDs with a density of 65 Gbi ts / in 2 over two orders of magnitude greater than the state-of-the-art magnetic storage density have been demonstrated. A method for mass production of QMD without employing lithography is discussed.

Quantum Chaotic Scattering and Resistance Fluctuations in Mesoscopic Junctions
Using the semiclassical approximation we calculate the quantum fluctuations of the two-dimensional electronic scattering cross-section from three hard disks in a magnetic field. The three-disk billiard is a schematic model for a three-lead mesoscopic (ballistic) junction. As the magnetic field increases the classical trajectories in the three-disk billiard undergo a hyperbolic±non-hyperbolic tr...

متن کاملThe effect of first order magnetic field in a GaAs/AlAs spherical quantum dot with hydrogenic impurity
In this research, the effect of the first order magnetic field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot has been calculated. The perturbation method has been used within the framework of effective mass approximation for these calculations. Overall, the analysis shows that a proper choice of quantum dot radius and magnetic field can signifi...
