Analysis of structural, morphological and magnetic properties of diluted magnetic semiconductor ZnO:Eu obtained by combustion reaction

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...

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

The effect of molar ratio on structural and magnetic properties of BaFe12O19 nanoparticles prepared by sol-gel auto-combustion method

Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium hexaferritefine particles is influenced by mo...

The Interplay Of Size- And Site-Dependence Of Magnetic Properties Of Diluted Magnetic Semiconductor Quantum Dots

Magnetic 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...
