In this work we propose and demonstrate the integration of ferromagnetic nanosized cobalt barrier gates in quantum dots arrays on FD-SOI nanowires. This innovative structure enhances both driving and addressability, while minimizing decoherence fields for electron spin qubits. Charge noise spectra show $sub-10-^6 e^2Hz-^1$ values at 1Hz, demonstrating a low- noise impact from Co gates. Our double dot experimental data show stable quantum confinement at 10mK and full multi-gate FET functionality. Based on calibrated magnetic simulations, we investigate and discuss the advantages of exploiting simultaneously electrical and ferromagnetic properties of gates. The record small achieved dot-magnet distance is below 10nm, with a footprint of the magnetic gates of 30x70nm2 on dots area, the smallest reported to date on a qubit structure, with a Rabi frequency of 282MHz and qubit addressability of 1.069GHz. This novel architecture paves the way to large-scale integration of qubits arrays with unprecedented magnetic control.
