بررسی‌های ساختاری و مغناطیسی نانوذرات‌ پروسکایت LaMn1-xCoxO3 (0/1، 75/0، 5/0، 25/0، 0/0 = x)

In this work, the structural and magnetic properties of LaMn1-xCoxO3 (x = 0.00, 0.25, 0.50, 0.75, 1.00) are investigated. The structural characterization of compounds by X-ray powder diffraction is evidence for a rhombohedral structure (R -3c space group). Much less increase of the unit cell volume suggests that Co enters in lattice as Co+2 for x ≤ 0.5 while much more decrease of the unit cell ...

OPTICAL PROPERTIES OF CO-EVAPORATED THIN FILMS OF BINARY Bi 0-Te 0 AND Bi 0 -V 0 SYSTEMS

Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...

ساخت نانو بلورک‌های δ-7O3Cu2YBa به روش مکانوشیمیایی و بررسی دمای گذار ترکیبات -7O3Cu2YBa(x-1) + 2 xMnO (02/0 ،015/0 ،01/0 ،005/0 ،0 = x)

In this research, YBa2Cu3O7-d (0 < d < 1) nanocrystalite superconductor was prepared by mechanochemical alloying method. We synthesized YBa2Cu3O7-d via mixing the BaCO3, Y2O3, CuO powders and milling in SPEX 8000 for 5h with weight ratio of ball to powder 10:1 and steel balls of 11mm diameter, followed by heating for 4h at 850 ˚C. The superconductor phase formation process was completed with si...
