Abstract
The effect of spin valve (SV) resistance, SV/lead contact resistance, heat conductance and heat capacitance of SV, and the blocking temperature of antiferromagnetic (AF) material in the SV on electrostatic discharge (ESD)-voltage was studied with test-elements in which the lead structure and the AF film were varied. Reducing SV/lead contact resistance by means of using lead-overlaid structure showed the largest effect on ESD-robustness among those factors
