CdTe And CdTe : Hg alloys crystal growth using stoichiometric and off-stoichiometric zone passing techniques

2014 Some aspects of the thermodynamic state of CdTe crystals grown by different zone passing techniques (sealed ingot zone refining technique and THM in tellurium solvent) are considered with regard to the general objective of getting high resistivity crystals. A vapour growth technique, called sublimation THM, which reduces several drawbacks of classical THM using a tellurium solvent, is deve...

Volume anomaly in ferrimagnetism

2014 The volume anomaly 0394V/V due to the magnetic energy corresponding to the exchange interactions is experimentally determined for YIG. The experimental values (from 77 K to Tc) agree with the values deduced from the theoretical expression based on the Néel’s theories of volume anomaly and of ferrimagnetism. These results are compared with those obtained by other authors on ferromagnetic an...

The Off-Stoichiometric Bi1.8Pb0.3Sr2Ca2Cu3.3Ox Target for Thin Films

X-ray diffraction (XRD), EDAX, AC susceptibility and resistivity measurements has been used as characterization methods for the Bi-2223 monophase target with the starting stoichiometry Bil.8F%,.3Sr2Ca2C~3.3 a. Pressure parameter is playing an important role in obtaining good superconducting properties for this compound. Critical currents and activation energy has been calculated from susceptibi...
