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 کاملTransport and magnetic properties of the diluted magnetic semiconductors
We report on electrical transport and magnetic properties of quaternary single crystals of Sb 1.98–x V 0.02 Cr x Te 3 and Sb 1.984–y V 0.016 Mn y Te 3 with x ranging from 0 to 0.022 and y ranging from 0 to 0.034 over temperatures from 2 K to 300 K. Ternary crystals Sb 2–z V z Te 3 were reported to have rather small magnetization in the ferromagnetic state due to low spin of vanadium ions. There...
متن کاملIII-V diluted magnetic semiconductor: Substitutional doping of Mn in InAs.
Local structures around Mn in In12xMnxAs films grown by molecular-beam epitaxy have been studied by using Mn K-edge extended x-ray-absorption fine-structure ~EXAFS! technique. Substitution of Mn atoms for the In sites is found in samples either grown at low substrate temperatures ~near 200 °C! or with a low Mn concentration ~about 1 at. %!. This result represents a significant extension of an e...

متن کاملMagnetic properties of diluted magnetic „ Gd , Lu ...
The magnetic susceptibility of the diluted magnetic Lu22xGdxO3 ~x50.06, 0.10, 0.22, 0.40, 1.00, 1.40, 1.80! was measured in the temperature range 1.7–295 K. The inverse susceptibility changes slope to a smaller value below 2.2 K for the samples with x<0.40. In the cubic Lu0.20Gd1.80O3 the slope increases below 2.8 K. These changes are attributed to the large difference in susceptibility for two...
