ANALYSIS OF SOME MAGNETIC PROPERTIES OF DILUTED MAGNETIC SEMICONDUCTORS
The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
متن کاملPb–Graphene–Pb Josephson Junctions: Characterization in Magnetic Field
We fabricate superconductor–graphene– superconductor Josephson junctions with superconducting regions made of lead (Pb). The critical current through graphene may be modulated by the external magnetic field; the resulting Fraunhofer interference pattern shows several periods of oscillations, suggesting that the junction is uniform. Deviations from the perfect Fraunhofer pattern are observed, an...
متن کاملDesignated magnetic field design for magnetic drug guidance in BNCT
In this paper, a local magnetic field was designed and simulated using a Helmholtz coil along with a ferromagnetic core with an appropriate geometric Structure to concentrate a magnetic flux. This field can be used for magnetic guiding of Boron-borne drugs in BNCT.
متن کاملMagnetic domains in III-V magnetic semiconductors
Recent progress in the theoretical understanding of magnetic anisotropy and stiffness in III-V magnetic semiconductors is exploited for predictions of magnetic domain characteristics and methods of their tuning. We evaluate the width and the energy of domain walls as well as the period of stripe domains in perpendicular films. The computed stripe width W51.1 mm for Ga0.957Mn0.043As/In0.16Ga0.84...
