This paper presents structural, magnetization and transport properties measurements carried out on as-deposited Co (400Å) thin film as well as samples annealed in the temperature range 100–500°C in steps of 100°C for 1h. The samples used in this work were deposited on float glass substrates using ion beam sputtering technique. The magnetization measurements carried out using MOKE technique, clearly...
This article describes a systematic study of the nature of interfaces involved in a Nb layer deposited on Si (Nb-on-Si) and Si layer deposited on Nb (Si-on-Nb) bilayer films by using a UHV electron beam evaporation technique, having individual layer thickness of 35 and 100A each. By using Grazing angle X-ray reflectivity and adopting a proper modelling technique the electron density profile (EDP)...
An amorphous iron nitride thin film was deposited using reactive ion beam sputtering of iron by a beam of argon and nitrogen ions. Nitrogen content in the film as determined from conversion electron Mossbauer spectroscopy (CEMS) and X-ray photoelectron spectroscopy (XPS) was FeN 0.7 . The mass density of the film was calculated using energy-dispersive X-ray reflectivity (EDXRR) measurements...
Effect of interfacial roughness on giant magnetoresistance (GMR) in Fe/Cr multilayers has been studied. A set of samples is prepared by simultaneously depositing on a set of float-glass (FG) substrates with varying rms surface roughness. This causes the correlated part of the rms roughness to vary from sample to sample. Another set of specimen is irradiated with 200MeV Ag ions in order to induce uncorrelated...
The behavior of superconducting transition temperature T C in superconducting/ferromagnetic (S/F) multilayers as a function of different layer thicknesses and for varying magnetic moment μ B of the F layer atoms is studied. Multilayer structures consist of five bilayers of constant superconducting Nb layer thickness of 400 9 and Fe of 6 and 24 9 each. The analysis of the magnetization...
