(a) Magnetic field and spin directions along the beam axis for the diabatic (upper) and the adiabatic (lower) cases. (b) Schematic for the spin flipper. The magnetic shield consists of a soft iron shield and two Permalloy shields . The magnetic field inside the flipper is controlled with three coils . The opposing field at the center of the shield is actually formed by the residual leakage field from the main magnet (dashed arrow) and the opposite field generated with . forms a transverse field for the adiabatic case.

The magnetic field distribution simulated using the FEMM software (Ref. 21). The problem is axisymmetric because a cyrindrical magnetic shield is placed along the axis of superconducting soilenoid magnet. (a) shows a slice of axisyemmetric field distribution in the total space. The detailed distribution around the magnetic shield is shown in (b). The center of the magnetic shield is located apart from the center of superconducting magnet.

The asymmetry of the sample current defined by Eq. (1) as a function of the magnetic field applied perpendicular to the Fe (7 ML)/Cu(100) surface. The measurement was conducted at the zero sample bias. The data acquisition time is /point. The inset shows the magnetic field dependence in the sample current.
