A concept of a planar vector magnetic sensor comprising in-plane tunnel magnetoresistive (TMR) sensors and an active flux-guide (AFG) was introduced in this work. The AFG redirected the magnetic flux at high-frequency benefiting a vertical detection capability and suppressing the field noise of the TMR at low-frequency measurement. The vertical sensitivity of V/T was close to the in-plane sensitivity of V/T. | Application of the flux bending effect in an active flux-guide for low-noise planar vector TMR magnetic sensors
