Low Voltage I-V Characteristics in Magnetic Tunnel Junctions [PDF]

open access: yes, 2001
We show that elastic currents that take into account variations of the tunnel transmitivity with voltage and a large ratio of majority to minority spin densities of states of the $s$ band, can account for the low voltage current anomalies observed in ...
