Magnetoresistivity of micron size (10{center{underscore}dot}0) epitaxial Co wires
Magnetoresistivity effects in association with the magnetic domain structure were studied by using 1 {micro}m wide epitaxial (10{center{underscore}dot}0) Co wires oriented parallel and perpendicular to the magnetic easy [001] axis. The parallel wire exhibited a large anisotropy magnetoresistivity ratio of {approximately}11% at 5 K, which turned to be negative above 214 K due to the temperature variable anisotropic magnetoresistivity effect. A negative domain wall contribution to the resistivity was observed only in the temperature range from 200 K to 220 K. On the contrary, the perpendicular wire exhibited a small positive wall contribution ranging from 3 x 10{sup {minus}4} {micro}{Omega}cm at 5 K to 6.9 x 10{sup {minus}4} {micro}{Omega}cm at 300 K.
