Effect of Magnetic Field on Surface Morphology and Magnetic Properties of FeCu/Cu Nano layers Prepared by Electrodeposition Technique: Investigation of Magneto-hydrodynamic Effect

در اين مقاله تاثير ميدان مغناطيسي بر مورفولوژي سطح، ساختار و خواص مغناطيسي لايه نازك FeCu/Cu بررسي شد. لايه نازك با روش نشست الكتروشيميايي تحت كنترل پتانسيل ثابت بر روي شيشه/Au2PdAgتهيه شد. طي نشست الكتروشيميايي ميداني معادل 5000 و 7000 اورستد اعمال شد. لايه نازك در دو شرايط حضور و غياب ميدان مغناطيسي تهيه و مقايسه گرديد. نتايج نشان داد كه ميدان مغناطيسي بر مورفولوژي سطح، ساختار و خواص مغناطيسي لايه نازك FeCu/Cuتاثيرگذار است . فيلم تهيه شده توسط پراش اشعه X ، ميكروسكوپ الكتروني روبشي، مغناطيس سنج ارتعاشي نمونه و آناليز EDSبررسي شد.

In this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited FeCu/Cu thin films was investigated. The films were deposited on Au2PdAg/glass substrates using electrodeposition technique in potentiostatic control. The magnetic fields of 5000 and 7000 Oe were applied on deposition bath during deposition. Two series of thin films were prepared in the same deposition conditions, one in the presence and the other in absence of magnetic field and the products were compared. The results indicate that applying the magnetic field has a significant effect on the growth process, i.e. morphology, crystal structure and magnetic properties of the films. The morphology and structure of the FeCu/Cu Nano layers were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The weight percentages of the elements in the deposited multilayers were determined by energy dispersive X-ray spectroscopy (EDS). Magnetic properties of thin films were studied using the vibrating sample magnetometer (VSM).
