      abstract     = {The structural and magnetic properties of YVO3, NdVO3 and
                      TbVO3 were investigated by single-crystal and powder neutron
                      diffraction. YVO3 shows a structural phase transition at 200
                      K from an orthorhombic structure with the space group Pbnm
                      to a monoclinic one with the space group P2(1)/b. But
                      supplementary high-resolution synchrotron diffraction
                      experiments showed that the monoclinic distortion is
                      extremely small. A group theoretical analysis shows that
                      this magnetic state in the monoclinic phase is incompatible
                      with the lattice structure, unless terms of higher than
                      bilinear order in the spin operators are incorporated in the
                      spin Hamiltonian. This observation is discussed in the light
                      of recent theories invoking unusual many-body correlations
                      between the vanadium t(2g) orbitals. A structural phase
                      transition back to the orthorhombic space group Pbnm is
                      observed upon cooling below 77 K. This transition is
                      accompanied by a rearrangement of the magnetic structure
                      into a mode compatible with the lattice structure. The
                      crystal structures of NdVO3 and TbVO3 are closely similar to
                      that of YVO3. However, only a single magnetic phase
                      transition was found in the vanadium sublattice down to 9.5
                      K. Below 60 K the magnetic moments of the Nd3+- and
                      Tb3+-ions are gradually polarized by the ordered vanadium
                      moments. Below 11 K, we found a noncollinear order of the
                      terbium moments.},
