Gate-controlled magnetic properties of the magnetic semiconductor (Zn,Co)O

Fabrication of ZnCoO nanowires and characterization of their magnetic properties

Hydrogen-treated ZnCoO shows magnetic behavior, which is related to the formation of Co-H-Co complexes. However, it is not well known how the complexes are connected to each other and with what directional behavior they are ordered. In this point of view, ZnCoO nanowire is an ideal system for the study of the magnetic anisotropy. ZnCoO nanowire was fabricated by trioctylamine solution method un...

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...

Effect of static magnetic field on the hemodynamic properties of blood flow containing magnetic substances

The use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. Considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...

Thermoelectric, transport, and magnetic properties of the polaron semiconductor FexCr3ÀxSe4

The series of compounds FexCr32xSe4, with 0<x<3, has been prepared and various thermoelectric properties measured from 5 to 900 K. Unlike most thermoelectric materials that are band semiconductors with high carrier mobilities, FexCr32xSe4 are polaronic semiconductors with Hall mobility values, over 100 times smaller. Nevertheless, FexCr32xSe4 has a surprisingly high thermoelectric figure of mer...
