Magneto-transport properties of NiMnSb thin films on InSb single crystals: Negative giant magnetoresistance
Gardelis, S.; Androulakis, J.; Viskadourakis, Z.; Papadopoulou, E. L.; Giapintzakis, John; Rai, S.; Lodha, G. S.; Roy, S. B. (2007)In this study we investigated the magneto-transport properties of the ohmic contact between polycrystal-line NiMnSb thin films grown by pulsed laser deposition and n-type degenerate InSb (100) substrates. An unusual negative ...

Negative giant longitudinal magnetoresistance in NiMnSb InSb: Interface effect
Gardelis, S.; Androulakis, J.; Viskadourakis, Z.; Papadopoulou, E. L.; Giapintzakis, John; Rai, S.; Lodha, G. S.; Roy, S. B. (2006)We report on the electrical and magnetotransport properties of the contact formed between n -type degenerate InSb (100) substrates and polycrystalline NiMnSb thin films grown using pulsed laser deposition. Negative giant ...

Surface and interface study of pulsed-laser-deposited off-stoichiometric NiMnSb thin films on a Si(100) substrate
Rai, S.; Tiwari, M. K.; Lodha, G. S.; Modi, M. H.; Chattopadhyay, M. K.; Majumdar, S.; Gardelis, S.; Viskadourakis, Z.; Giapintzakis, John; Nandedkar, R. V.; Roy, S. B.; Chaddah, P. (2006)We report a detailed study of surface and interface properties of pulsed-laser-deposited NiMnSb films on a Si(100) substrate as a function of film thickness. As the thickness of films is reduced below 35 nm, formation of ...
