In this work we have investigated the changes of the magnetic properties of highly oriented pyrolytic graphite samples after irradiation either with ~3×10<Superscript>14</Superscript> protons or 3.5×10<Superscript>13</Superscript> ... 3.5×10<Superscript>14</Superscript> iron ions with energies in the MeV range. Our results show that iron and proton irradiations can...</superscript></superscript></superscript>

We investigated the shot noise properties in the diluted-magnetic-semiconductor/semiconductor heterostructures, where the sp-d exchange interaction gives rise to a giant spin splitting when an external magnetic field is applied along the growth direction of the heterostructures. It is found that...

The future of the spintronic technology requires the development of magnetic semiconductor materials. Most research groups have focused on diluted magnetic semiconductors because of the promising theoretical predictions and initial results. In this work, the current experimental situation of ZnO...

We theoretically calculate the Josephson current for two superconductor/ferromagnetic semiconductor (SC/FS) bilayers separated by a semiconductor (SM) layer. It is found that the critical Josephson current I<Subscript>C</Subscript> in the junction is strongly determined by not only the relative orientations of the...</subscript>

The magnetic and electrical properties of Co-implanted single crystalline TiO<Subscript>2</Subscript> rutile are presented. For fluences of the order of 10<Superscript>17</Superscript> cm<Superscript>-2</Superscript> and implantation energy of 150 keV the maximum atomic concentration of cobalt is 13 at% at a depth of 65 nm from the surface. The as implanted single...</superscript></superscript></subscript>

Theoretical studies on spin-dependent transport in magnetic tunnel heterostructures consisting of two diluted magnetic semiconductors (DMS) separated by a nonmagnetic semiconductor (NMS) barrier, are carried in the limit of coherent regime by including the effect of angular dependence of the...
