New types of spintronics devices utilizing all-electrical magnetization manipulation by current, such as spin-torque transfer RAM and spin-torque oscillators, have been developed based on MgO magnetic tunnel junctions (MTJs) [1]. Spin-torque oscillators based on MTJs with in-plane magnetization [2] show high frequency capabilities, but still need an external magnetic field and are characterized...

in this scientific research, magnesium oxide (mgo) nanoparticles were synthesized from magnesium nitrate and ammonium solutions via microwave@sol-gel process. the structure and the morphology of the synthesized nanoparticles has been identified and characterized by x-ray diffraction (xrd), n2-bet (brunauer-emmett-tell), scanning electron microscopy (sem) and fourier transform infrared (ftir) te...

This study focused on the utilization of nano-MgO as an energy-saving and eco-friendly stabilizer to improve engineering performance loess. To this end, loess samples at various contents curing times were prepared, then standard compaction, consistency limits, unconfined compression tests performed. The achieved results demonstrated that adding increased liquid limit, plastic optimum water cont...

Abstract: Multiwalled carbon nanotubes (MWCNTs) were coated with MgO nano particles using simple precipitationmethod. The growth of Mg(OH)2particles was controlled by adjusting the alkaline concentration, salt concentrationand feed rate in simple precipitation method. The nanometer-sized Mg(OH)2particles were precipitated on the surfaceof functionalized MWCNTs by reaction between MgSO4 solution...

materials and methods in this experimental study, nmri male mice were placed in groups receiving atropine (0.1 and 1 mg/kg), recipient of mgo-n (1, 2.5, and 5 mg/kg) and groups receiving atropine in effective dose and different doses of mgo-n were used. saline was used as a vehicle for drugs in the control groups. memory was evaluated with a step-down apparatus to determine the coming down late...

This paper presents the spin sensitivity and magnetic response analysis of nano-superconducting-quantum-interference devices (SQUIDs). We employed computational study to understand schemes a nano-SQUID’s detection capability according device’s geometry fabrication process. find that performance nano-device increased by decreasing loop size SQUIDs, it reached maximum value at corners loop. then ...
