Orbital Magnetic Ordering in Disordered Mesoscopic Systems
نویسنده
چکیده
We present some model calculations of persistent currents in disordered oneand two-dimensional mesoscopic systems. We use the tight-binding model and calculate numerically the currents in small systems for several values of disorder. Next we fit appropriate analytical formulae, and using them we find self-sustaining currents and critical fields in larger, more realistic systems with different shapes of the Fermi surfaces (FS). PACS numbers: 71.30.+h; 72.10.-d; 72.90.+y

In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
متن کاملEffect of short range order on electronic and magnetic properties of disordered Co based alloys
We here study electronic structure and magnetic properties of disordered CoPd and CoPt alloys using Augmented Space Recursion technique coupled with the tight-binding linearized muffin tin orbital (TB-LMTO) method. Effect of short range ordering present in disordered phase of alloys on electronic and magnetic properties has been discussed. We present results for magnetic moments, Curie temperat...
متن کاملA New Intrinsic Magnetic Property Due to the Mesoscopic Ordering of Cobalt Nanocrystals in Supra-Crystals
Recently, it has been shown that nanoparticles with a narrow size distribution can self-organize into highly ordered fcc supra-crystals. This new generation of materials have been found to exhibit unique collective properties, which arise from the periodic ordering of the nanoparticles. Using the expertise we have to control the ordering of cobalt nanoparticles in 3D assemblies, we have been ab...

We study the orbital magnetism of 2D lattices with chaotic motion of electrons withing a primitive cell. Using the temperature diagrammatic technique we evaluate the averaged value and rms fluctuation of magnetic response in the diffusive regime withing the model of non-interacting electrons. The fluctuations of magnetic susceptibility turn out to be large and at low temperature can be of the o...

All seven physics STAIRSTEP students and 15 undergraduate students have participated to a talk about the orbital magnetic susceptibility of electrons in a rectangular box. Mesoscopic systems, such as small metal particles and quantum dots, exhibit many novel properties due to the coherent effect and finite-size quantization. In the mesoscopic regime, magnetic properties are sensitive to whether...
