Ferromagnetic tunnel junctions with naturally oxidized Al barriers were fabricated by magnetron sputtering. Using metal masks, 0.01 mm^2 junction areas were patterned. Junctions with slightly oxidized Al barriers showed small tunnel resistances. Of those, some had extraordinarily large MR ratios, others had different tunnel rests-tances according to different current-flow paths, and some had characteristics of both. In contrast, junctions with well oxidized Al barriers exhibited a large tunnel resistance and good stability. The Ni-Fe/Co/Al-A10_x/Co/NiFe/Fe -Mn/Ni -Fe junction showed spin-valve-like R-H properties. The MR ratio was 10% for a 2O Oe magnetic field.
