“…Egelhoff et al have considered experimentally and theoretically the possibility that, in the case of Ni, Fe or Co electrodes, the magnetostriction can contribute to the observed large values of magnetoresistance [14]. Nevertheless, Garcia et al have offered recently the experimental evidence excluding the magnetostriction as the origin of the "BMR" [21].…”

“…However, these reports do not offer a clear manufacturing concept that can be further extended towards device design. The poor characterizations of the nanocontact size and structure is some BMR reports have left a room for extensive discussions regarding the true origin of their magnetoresistance 9,10 .…”

Point contacts of magnetite exhibit large, reversible increases of conductance by a factor of up to 5 in the presence of a small magnetic field ͑Ͻ10 mT͒, provided the conductance is less than the quantum of conductance G 0 ͑12 900 ⍀͒ −1 . Smaller effects are found in ͑La 0.7 Sr 0.3 ͒MnO 3 and Co 2 Cr 0.6 Fe 0.4 Al. Comparable effects observed in magnetite nanoconstrictions milled using a focused-ion beam in thin films deposited on oxide substrates are only reversible on a time scale of hours. High-resistance nanogaps show evidence of field emission beyond a voltage threshold, which is itself field dependent. The results are discussed in terms of spin-polarized transport, magnetostriction, magnetic dipole strain, and Fowler-Nordheim tunneling.
