It is shown that the magnetoresistive response depends critically on the M[...]texto impreso
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[...]
