Magnetic correlations in the disordered ferromagnetic alloy Ni-V revealed with small angle neutron scattering

We present small angle neutron scattering (SANS) data collected on polycrystalline Ni1−xVx samples with x ≥ 0.10 with confirmed random atomic distribution. We aim to determine the relevant length scales of magnetic correlations in ferromagnetic samples with low critical temperatures Tc that show sig...

Summary:We present small angle neutron scattering (SANS) data collected on polycrystalline Ni1−xVx samples with x ≥ 0.10 with confirmed random atomic distribution. We aim to determine the relevant length scales of magnetic correlations in ferromagnetic samples with low critical temperatures Tc that show signs of magnetic inhomogeneities in magnetization and μSR data. The SANS study reveals signatures of long-range order and coexistence of short-range magnetic correlations in this randomly disordered ferromagnetic alloy. We show the advantages of a polarization analysis in identifying the main magnetic contributions from the dominating nuclear scattering.
