Effect of surface morphology on magnetization dynamics of cobalt ultrathin films
Anup Kumar Bera, Pooja Gupta, Debi Garai +1
Growth of Co film on SiO2 substrates with the surface roughness of 0.5 nm and 1.6 nm has been studied in situ using the magneto-optical Kerr effect (MOKE) and four probe resistivit…
Influence of interface and microstructure on magnetization of epitaxial Fe4N thin film
Nidhi Pandey, S. Putter, S. M. Amir +5
Epitaxial Fe4N thin films grown on lattice-matched LaAlO3 (LAO) substrate using sputtering and molecular beam epitaxy techniques have been studied in this work. Within the sputteri…
Magnetism and structure of in-situ grown FeN films studied using N K-edge XAS and nuclear resonance scattering
Mukul Gupta, Nidhi Pandey, Niti +5
We studied the structural and magnetic properties of \textit{in-situ} grown iron mononitride (FeN) thin films. Initial stages of film growth were trapped utilizing synchrotron base…
In situ soft x-ray absorption spectroscopic study of Fe/MgO interfaces
Pramod Vishwakarma, Mukul Gupta, D. M. Phase +1
Interfacial reaction between iron and MgO has been studied in situ during deposition of iron on MgO surface, using soft x-ray absorption spectroscopy. High sensitivity of the techn…
Interface Sharpening in Miscible and Isotopic Multilayers: Role of Short-Circuit Diffusion
Atul Tiwari, M. K. Tiwari, Mukul Gupta +2
Atomic diffusion at nanometer length scale may differ significantly from bulk diffusion, and may sometimes even exhibit counterintuitive behavior. In the present work, taking Cu/Ni…
Sign Reversal and Tunability of Exchange Bias in Nanoscale AuFe Alloy Film: A New Material for Spintronic Application
Compesh Pannu, Santanu Ghosh, Pankaj Srivastava +5
We report here sign reversal and tunability of exchange bias in AuFe cosputtered films of thickness about 63 nm. As deposited film exhibits exchange bias effect at room temperature…
