The magnetoresistive properties of pinned spin valves (SV) and their roles in low-field sensing applications were characterized. The magnetoresistive parameters were extracted, including the exchange bias (Heb) field as a function of the iron content in the CoFe layer and the antiferromagnetic (AFM) thickness, the magnetoresistance (MR) ratio versus the spacer thickness, the coercivity (Hc) as a function of the seed layer, and the composite layer [NiFe/Co] used.

This study was aimed to evaluate the physicochemical properties and chemical profile of seeds oil obtained from new seven sunflower (Helianthus annuus L.) lines as well as their antioxidant and enzyme inhibition activity. The seeds powder was extracted by maceration in n-hexane. The oil content of the seven lines was ranged from 20.04% to 36.65% and was either yellow or pale yellow in color. No significant variations were observed on the refractive index (1.46 unit) of the oil.
