Electric field control of magnetism in Si3N4 gated Pt/Co/Pt heterostructures
Jaianth Vijayakumar, David Bracher, Tatiana M. Savchenko +3
In this work we show the presence of a magnetoelectric coupling in silicon-nitride gated Pt/Co/Pt heterostructures using X-ray photoemission electron microscopy (XPEEM). We observe…
The new neutron grating interferometer at the ANTARES beamline - Design, Principle, and Applications -
Tommy Reimann, Sebastian Mühlbauer, Michael Horisberger +2
Neutron grating interferometry is an advanced method in neutron imaging that allows the simultaneous recording of the transmission, the differential phase and the dark-field image.…
Effect of Al doping on phase formation and thermal stability of iron nitride thin films
Akhil Tayal, Mukul Gupta, Nidhi Pandey +3
In the present work, we systematically studied the effect of Al doping on the phase formation of iron nitride (Fe-N) thin films. Fe-N thin films with different concentration of Al…
Depth dependence of the ionization energy of shallow hydrogen states in ZnO and CdS
T. Prokscha, H. Luetkens, E. Morenzoni +5
The characteristics of shallow hydrogen-like muonium (Mu) states in nominally undoped ZnO and CdS (0001) crystals have been studied close to the surface at depths in the range of 1…
Effect of dopants on thermal stability and self-diffusion in iron nitride thin films
Akhil Tayal, Mukul Gupta, Ajay Gupta +4
We studied the effect of dopants (Al, Ti, Zr) on the thermal stability of iron nitride thin films prepared using a dc magnetron sputtering technique. Structure and magnetic charact…
Observation of slow order parameter fluctuations in superconducting films using beta-detected NMR
E. Morenzoni, H. Saadaoui, D. Wang +11
We report beta-NMR investigations of polarized 8Li implanted in thin Pb and Ag/Nb films. At the critical superconducting temperature, we observe a singular peak in the spin relaxat…
Formation of iron nitride thin films with Al and Ti additives
Rachana Gupta, Akhil Tayal, Mukul Gupta +3
In this work we investigate the process of iron nitride (Fe-N) phase formation using 2 at.% Al or 2 at.% Ti as additives. The samples were prepared with a magnetron sputtering tech…
Fe and N self-diffusion in non-magnetic Fe:N
M. Gupta, A. Gupta, R. Gupta +3
Fe and N self-diffusion in non-magnetic FeN has been studied using neutron reflectivity. The isotope labelled multilayers, FeN/57Fe:N and Fe:N/Fe:15N were prepared using magnetron…
Fe and N self-diffusion in amorphous FeN: A SIMS and neutron reflectivity study
S. Chakravarty, M. Gupta, A. Gupta +6
Simultaneous measurement of self-diffusion of iron and nitrogen in amorphous iron nitride (Fe86N14) using secondary ion mass spectroscopy (SIMS) technique has been done. In additio…
Development of an Indium Bump Bond Process for Silicon Pixel Detectors at PSI
Ch. Broennimann, F. Glaus, J. Gobrecht +7
The hybrid pixel detectors used in the high energy physics experiments currently under construction use a three dimensional connection technique, the so-called bump bonding. As the…
Magnetoresistance Anisotropy of Polycrystalline Cobalt Films: Geometrical-Size- and Domain-Effects
Woosik Gil, Detlef Goerlitz, Michael Horisberger +1
The magnetoresistance (MR) of 10 nm to 200 nm thin polycrystalline Co-films, deposited on glass and insulating Si(100), is studied in fields up to 120 kOe, aligned along the three…
Observation of non-exponential magnetic penetration profiles in the Meissner state - A manifestation of non-local effects in superconductors
A. Suter, E. Morenzoni, N. Garifianov +5
Implanting fully polarized low energy muons on the nanometer scale beneath the surface of a superconductor in the Meissner state enabled us to probe the evanescent magnetic field p…
