Magnetoresistance in Co/AlOx/Co tunnel junction arrays
2002 (English)In: Journal of Magnetism and Magnetic Materials, ISSN 0304-8853, Vol. 249, 513-518 p.Article in journal (Refereed) Published
Lateral arrays of Co/AlOx/Co junctions with dimensions down to 60 nin and inter-junction separations similar to60-100 nm have been fabricated and analyzed for possible coherent tunneling effects. Extra attention is paid to avoid uncertainties due to inconsistencies in switching and/or resistance of successive barriers. We observe similar to10% magnetoresistance enhancement at moderate bias in double junctions that cannot be accounted for by a simple model of two resistsors in series.
