Enhancement of room-temperature magnetoresistance in La0.5Sm0.2Sr0.3MnO3/(Ag2O)x/2PENG Zhenshenga, b, WANG Guiyinga, TANG Yongganga, LIU Penga, and NIU Xiaofeia a Anhui Key Laboratory of Spintronics..., and magnetoresistance effect were studied through the measurement and fitting of ρ-T curves. The results show that the element Ag takes part in reaction when the doping amount is small. Ag is mainly distributed......
, Buffalo, NY 14260, USA Received 10 April 2006; accepted 25 April 2006 Abstract: Recent work on magnetic quantum point contacts (QPCs) was discussed. Complete magnetoresistance loops across Co QPCs as small as a single atom was measured. The remarkable feature of these QPCs is the rapid oscillatory decay in magnetoresistance with the increase of contact size. In addition, stepwise or quantum......
Peculiarity of magnetoresistance of discontinuous ferromagnetic thin filmsYu.O.Shkurdoda,I.M.Pazukha,A.M.ChornousDepartment of Applied Physics,Sumy State University摘 要:magnetoresistance(MR) was observed for all of the as-deposited samples. The maximum MR was observed for Fe thin films with an effective thickness of 17 nm. In the case of the Co thin films......
