A miniaturised versatile spin rotator for application in neutron interferometer experiments is developed. The coil design without material in the beam path allows for a magnetic field adjustable to an arbitrary direction perpendicular to the neutron beam. The field simulations show a homogeneous field over the beam cross-section of 8 mm x 5 mm and a field transition less than or similar to 20 mm from inside to outside. The performance of the fabricated miniaturised coil was quantified by carrying out the polarimeter experiment of Demirel et al (New I. Phys., 17:023065, 2015) regarding spin-rotation coupling. The high efficiency spin manipulations by the implemented rotating magnetic field results in a linear dependence between the phase shift and the rotation frequency. In near future, the spin rotator will be used to investigate spin-rotation coupling in a related interferometer experiment.
