AbstractThe detection of weak magnetism requires magnetoresistance (MR) sensors with low switching field (HSW). Conetic-based synthetic ferrimagnet (SF) is engaged as free layer in spin valves in order to reduce HSW. Low coercivity is achieved through adapting synthetic antiferromagnetic pinned layer. MR ratio, coercivity and HSW increase with the Conetic alloy thickness in SF free layer. Through introducing CoFeB/SF free layer, MR ratio of 0.6 % and small coercivity of 0.2 Oe are attained, which holds promise for low-field sensing applications. © 2016 IEEE.
