MgO based specular spin valve with reversible minor loop and higher exchange bias for futuristic linear magnetic field sensor

•Study of effect of non-magnetic MgO specular layer in GMR characteristics.•A comparative analysis with conventional and naturally oxidized specular system.•Reversible minor loop and large exchange bias were achieved in MgO system.•Higher Heb is explained by the discrepancy in the oxide/FM interface...
