Volume 2, Issue 2 , 2017, , Pages 76-79

  Thin films of Co2MnSi are grown on n-doped Si (100) and SiO2 (100) substrates by RF sputtering. The deposition time to grow the films is varied, once for ten minutes and another for an hour at a particular substrate temperature 600oC and keeping all the other parameters same. The Co2MnSi thin films deposited ...  Read More

Volume 1, Issue 1 , 2016, , Pages 21-24

  A proximity-induced superconductivity is used in a single crystal flake Bi2Te3 topological insulator to probe the behavior of magnetoresistance around the local superconducting critical fields. The magnetoresistance in Bi2Te3 and GaAs materials with superconducting contacts are studied and compared. ...  Read More
