We present a concept for a compact magnetostatic cavity called a “Magic box” that provides a very homogeneous magnetic environment for a polarised 3He neutron spin-filter cell in the presence of moderate magnetic stray fields. Based on this conce

Magnetic domain walls in thin films can be well analyzed using polarized neutron reflectometry. Well defined streaks in the off-specular spin-flip scattering maps are explained by neutron refraction at perpendicular N\'{e}el walls. The position of th

A new filling station for nuclear polarisation of 3 He gas has been constructed at the ILL, Grenoble. The “Tyrex” machine uses metastability-exchange optical pumping for polarising the 3 He gas at about 1 mbar pressure. The gas is then compressed

We report on the use of the polarized $^3$He gas filter and neutron resonant enhancement techniques for the measurement of spin-polarized diffuse neutron scattering due to ferromagnetic domains. A CoO/Co exchange biased bilayer was grown on a Ti/Cu/$

The poor knowledge of the spin-dependent neutron scattering length of 3He has until now handicapped nuclear four body theory and the interpretation of excitations in the quantum liquid. We have measured, for the first time directly, the real part of

The strongly spin-dependent absorption of neutrons in nuclear spin-polarised 3 He opens up the possibility of polarising neutrons from reactors and spallation sources over the full kinematical range of cold, thermal and hot neutrons. In this paper we

The precise knowledge of the neutron polarisation is needed in tests of the electroweak Standard Model using angular correlations in polarised neutron beta decay. We performed an experimental comparison study of two different methods of polarisation
