Alpha iron phthalocyaninesMössbauer spectroscopymagnetic interactionsAlpha iron phthalocyanines (α-FePc) oxygenated at low temperatures were investigated with the help of 57Fe Mössbauer spectroscopy, magnetization measurements (SQUID) and X-ray diffractometry (XRD). Mössbauer spectroscopy revealed that ...
In the present work flower-like, alpha-Fe2O3 were synthesized by ethylene-glycol mediated polyol method. The synthesized flower-like, alpha-Fe2O3 were separated cadmium (Cd2+) chromium (Cr6+) and lead ions (Pb2+) from wastewater. XRD pattern and FESEM images show the obtained sample is...

The samples were characterized using scanning electron microscope (SEM), transmission electron microscope (TEM), x-ray diffraction (XRD), and x-ray photoelectron spectroscopy (XPS). It was found that annealing in ozone-rich environment for 2-4 h at 700 deg C yielded the best results in terms...
Their structures, magnetic properties and thermal stability were studied by X-ray diffraction (XRD), transmission electron microscope (TEM) and vibrating sample magnetometer (VSM). It was found that the saturation magnetization ( M s ) of α″-Fe 16 N 2 decreases with increasing temperat...
