Abstract
Giant magnetoresistance (MR) effects have been investigated for spin valve sandwiches using amorphous(a)‐(Co0.9Fe0.1)80B20 alloy layers. In an a‐CoFeB/Cu/Co sandwich, a MR ratio as large as 6% was obtained, and a MR curve was found to saturate in a field within 100 Oe. The resistivity is 40–60 μΩ cm. In a CoFeB(4 nm)/Cu(2 nm)/a‐CoFeB(2 nm)/NiO(10 nm) sandwich, MR ratios as large as 4% were also obtained. The maximum field sensitivity of the sandwich is about 2.5%/Oe.This publication has 4 references indexed in Scilit:
