Description

Magnetoresistivity effects in association with the magnetic domain structure were studied by using 1 pm wide epitaxial (10.0) CO wires oriented parallel and perpendicular to the magnetic easy (Ol) axis. The parallel wire exhibited a large anisotropy magnetoresistivity ratio of -11 % at 5 K, which turned to be negative above 214 K due to the temperature variable anisotropic magneto- resistivity 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 mcm at 5 K to 6.9 x 10" pQcm at 300 K.
