Cubic helimagnets with B 20 structure display several unusual properties such as anisotropy of the spin-wave spectrum al small momenta q , rotation of the helix vector k in magnetic field and quantum phase transition at pressure. We demonstrate that

In the external field slightly inclined to the $x$- or y-axis of the frustrated tetragonal atiferromagnet Pr2CuO4, a transition is discovered from the phase with orthogonal antiferromagnetic spin subsystems along [1,0,0] and [0,1,0] to the phase with

The problem of the inelastic nuclear-magnetic interference (INMI) in the scattering of the polarized neutrons in isotropic cubic dipolar ferromagnet is considered theoretically. It is shown that using polarized neutrons the contribution of INMI to th

Inelastic polarised neutron scattering is analysed when the magnetic interaction includes a part characterised by an axial vector. In this case the dynamical chiral (DC) scattering and inelastic nuclear-magnetic interference (INMI) may appear. As exa

The theoretical solution of the problem of neutron depolarization in magnetic materials with the presence of magnetic field is presented. The particular case, when an applied magnetic field is perpendicular to the neutron velocity, is considered. The

The problem of the inelastic nuclear-magnetic interference (INMI) at the scattering of the polarized neutrons is considered theoretically. General expressions for this interference are derived and discussed. It is shown that the INMI appears at the p

A crossover in the critical behaviour of the sublattice orientation to the external magnetic field in the vicinity of the second order spin-flop transition, H c , is demonstrated by the field dependence of a magnetic reflection intensity. A strong no

The population asymmetry of the left-right helixes in the strain-free holmium is shown by polarised neutrons to be less than 6 × 10−5. The interaction between the spin chirality and the elastic torsion is demonstrated, which provides a possibility
