摘要：
We studied magnetic properties and GMR effect of Cox − Cu100−x (10 ≤ x30 at%) microwires. We observed considerable magnetoresistance (MR), ΔR/R, in Co-Cu glass coated microwires with x = 10–30%. For low x content (x = 10), ΔR/R we observed negative MR, tending to saturate in high magnetic fields, H. On the other hand, for the samples x = 30 ΔR/R(H) dependences showed non-monotonic behavior, exhibiting ΔR/R increase with H at low H-values (up to 5 kOe) and also considerable GMR effect.
