Neutron diffraction experiments on nanocrystalline holmium suggest the absence of helifan(3/2) and helifan(2) structures at 50 K.
The results are reported of magnetic field-dependent neutron diffraction experiments on polycrystalline inert-gas c

A neutron study of nanocrystalline terbium (Balaji G et al 2008 Phys. Rev. Lett. 100 227202) has shown that the randomly oriented anisotropy of the paramagnetic susceptibility tensor may lead to strongly correlated nanoscale spin disorder in the para

We have studied the magnetization-reversal process of a Nd2Fe14B/Fe3B nanocomposite using small-angle neutron scattering. Based on the computation of the autocorrelation function of the spin misalignment, we have estimated the characteristic size lC

We report magnetic-field-dependent small-angle neutron scattering (SANS) experiments on a Nd2Fe14B/Fe3B nanocomposite. For the two scattering geometries where the applied magnetic field is either perpendicular or parallel to the incoming neutron beam
