Quasielastic Neutron Scattering Study of Reorienting di-heptyloxyazoxybenzene (HOAB) Molecules in the Nematic and Smectic C Phases

Quasielastic neutron scattering (QNS) measurements carried out for heptyloxyazoxybenzene (HOAB) revealed the existence of fast molecular reorientation in the nematic and smectic C phases. The correlation time of this process, derived by fitting to a uniaxial rotational diffusion model, is of order of 10–20 ps in both liquid crystal phases. An explanation of the reasons for the disagreement between the correlation time values obtained by methods based on QNS and dielectric relaxation in the microwave region is suggested.     

Neutron diffraction investigation of the atomic and magnetic structures of MnAs at high pressures

The atomic and magnetic structures of the MnAs compound are investigated using neutron diffraction at high pressures up to 38 kbar in the temperature range 15–300 K. It is found that, as the temperature decreases under high pressure, the MnAs compound undergoes a spin-reorientation transition from the ferromagnetic orthorhombic phase to a new phase whose magnetic moment has both the ferromagnetic and antiferromagnetic components. The structural and magnetic parameters of the high-pressure phases of the MnAs compound are determined.
