The Vision and Action Plan of the National Nanotechnology Initiative

Roco M., National Science Foundation, US

The vision of novel phenomena, unity in nature, and promise of the most efficient manufacturing length scale has been essential in establishing the multidisciplinary National Nanotechnology Initiative (NNI). The research opportunities and projections of their [...]

FE-Simulation of Fast Switching Behavior of Magnetic Nanoelements

Fidler J., Schrefl T., Forster H., Suess D., Dittrich R., Vienna University of Technology, AT

Numerical micromagnetics is an essential tool to optimize magnetic storage media, spin electronic devices, such as MRAM and microsensors. The application of these devices requires a profound knowledge of the reversal mechanism. In nanostructured magnets [...]

Development of a MEMS Vertical Planar Coil Inductor

Chen J., Zou J., Liu C., Kang S-M, Agere Systems, US

This paper presents the results of the development of a vertical planar coil inductor. The planar coil inductor is first fabricated on silicon substrate and then assembled to the vertical position by using a novel [...]

Magnetic Properties over Several Length Scales: Micro-magnetic Modeling and Effective Medium Theory

Harter A.W., Mohler G., Moore R., Schultz J., Georgia Tech Research Institute, US

We combine micro-magnetic modeling with effective medium theory to predict the bulk properties of magnetic composites, in particular those of ferrite particles in a non-magnetic matrix. We verify our model using published measured data of [...]

The Microstructure and Computed Magnetic Properties of Nanoscaled Permanent Magnets

Zhang J.X., Zhang T.J., Zhang J.X., Zhang T.J., Cui K., Key State Laboratory of Die Technology, HUST, CN

Magnetic properties of a model nanocomposite magnet were calculated by means of computer simulation, and the effects of the amount of the soft magnetic phase on them were studied. The numerical results show that the [...]

Latency Minimization for Permutations Using Distributed Technology

McAven L.F., Schlesinger M., Kent R.D., University of Windsor, CA

Distributed processing is a new concept considered as a solution to the cost problem relating to scaling parallel machines. Any problem given to a distributed system of n-processors can be better solved by a single [...]

Hopping and Correlation Effects in Atomic Clusters and Networks

Kulik I.O., Bilkent University, TR

Exact solution for hopping and correlation effects in atomic clusters and mesoscopic/nanoscopic networks is outlined. The program translates the Hamiltonian operator of the cluster written in terms of second-quantized creation and annihilation operators, to sparse [...]

The Distributive Calculation of Unitary Group Recoupling Coefficients

McAven L.F., Schlesinger M., Kent R.D., University of Windsor, CA

Symmetries, through group theory, can provide exact information about complex systems. However approximations are often made, for example density functionals are used in quantum chemistry, because it is impractical to obtain group coefficients. Coefficients for [...]
