Marcano, N. ; Sangiao, S. ; Magén, C. ; Morellon, L. ; Ibarra,, M. R. ; Plaza, M. ; Pérez García, Lucas | American Physical Society | 2010-09-29We have investigated the magnetotransport properties of ultrathin films of Bi grown on thermally oxidized Si(001) substrates with thickness ranging from 10 to 100 nm at temperatures down to 2 K and in magnetic fields up to 90 kOe. Remarkable dif[...]texto impreso
Marcano, N. ; Sangiao, S. ; Plaza, M. ; Pérez García, Lucas ; Fernández Pacheco, A. ; Córdoba, R. ; Sánchez, M. C. ; Morellon, L. ; Ibarra, M. R. ; De Teresa, J. M. | American Institute of Physics | 2010-02-22We study the electrical resistivity of individual Bi nanowires of diameter 100 nm fabricated by electrodeposition using a four-probe method in the temperature range 5-300 K with magnetic fields up to 90 kOe. Low-resistance Ohmic contacts to indi[...]
