Evidence of spin-wave demagnetization in Fe–Cr giant magnetoresistance multilayers
The temperature dependence of the saturation magnetization of Xe ion-beam sputtered Fe–Cr multilayers has been measured between 5 and 300 K in the presence of a field greater than the saturation field sHsatd. With the application of Hsat, the zero-field antiferromagnetically coupled ferromagnetic Fe layers are forced to align ferromagnetically. We find that the thermal demagnetization of such m...
متن کاملOxide formation and anodic polarization behavior of thin films of amorphous and crystalline Fe-Cr-P alloys prepared by ion beam mixing
An experimental program has been conducted to determine the effect of phosphorus on the corrosion and passivation behavior of Fe-Cr-P alloys. Chemically homogeneous 60 nm films of Fe-lOCr-xP (x from 0 to 35 at.%) were prepared by multilayer evaporation followed by ion beam mixing with Kr + ions. Films with a phosphorus content of at least 25 at.!% were found to be entirely amorphous, while film...
متن کاملMagnetic profiles and coupling in Fe/Cr(110) superlattices
In epitaxial Fe/Cr superlattices the coupling between the Fe layers oscillates between antiferromagnetic (AFM) and ferromagnetic as a function of the Cr layer thickness tCr. The period of the oscillation is the same for superlattices grown with (211) and (100) orientations. We measured the coupling of Fe/Cr(110) superlattices consisting of three identical Fe layers. The magnetization curves wer...
متن کاملStructure and magnetism of Fe/Si multilayers grown by ion-beam sputtering.
Ion-beam sputtering has been used to prepare Fe/Si multilayers on a variety of substrates and over a wide range of temperatures. Small-angle x-ray diffraction and transmission electron microscopy experiments show that the layers are heavily intermixed although a composition gradient is maintained. When the spacer layer is an amorphous iron silicide, the magnetic properties of the multilayers ar...
متن کاملیافته کوتاه: ارزیابی بخش های پایدار و ناپایدار فلزات سنگین (Fe, Mn, Cr, Ni) در رسوبات سطحی حوزه جنوبی دریای خزر دو ایستگاه( تنکابن و امیرآباد )
This study was conducted to determine some heavy metals (Fe, Mg, Cr, Ni) of surface sediment in the southern Caspian Sea during two seasons (Summer and Winter) in 2014-2015. 36 surface sediments samples (with triplicate) were collected at two stations (Tonekabon and Bandar Amirabad). All samples were analyzed using sequential extraction to indicate natural and anthropogenic sources. The results...
