Characterization of Nano-Magnet Ni100-xCux Alloys Electrodeposited onto (n-type) Si Substrates

در اين كار، خواص مغناطيسي لايه هاي آلياژي Ni100 - xCux تهيه شده به روش الكترو انباشت روي زيرلايه سيليكون نوع n مورد مطالعه قرار گرفته است . سطح نمونه ها توسط ميكروسكوپ الكتروني روبشي (SEM) آناليز شده، نسبت هاي واقعي نيكل و مس در تركيب بوسيله آناليز پرتوهاي ايكس اين دستگاه (EDS) بدست آمده، با نسبت هاي اسمي مقايسه گرديده است . منحني هاي پسماند مغناطيسي نمونه ها بوسيله مغناطوسنج نيروي گراديان متناوب (AGFM) رسم گرديده، تغيير خواص مغناطيسي با تغيير مقدار x مورد بررسي قرار گرفته است.

In this work the magnetic properties of Ni100-xCux alloy films of arbitrary composition, which are grown by electro deposition method onto (111) n-type silicon, has been studied. The surface of samples has been analyzed by Scanning Electron Microscopy (SEM). An Alternating Gradient Force Magneto metery (AGFM) device was used to prepare hysteresis loops of Ni100-xCux thin films electro deposited on Si and their magnetic properties were studied as a function of composition and concentration of Ni. Good control over the average composition of a Ni100-xCux alloy film has been achieved by using Energy-Dispersive X-Ray Spectroscopy (EDS) where the nominal compositions and the compositions measured for films consisting of different quantities of Cu and Ni deposited in alternation were compared
