## Description

- description: "We have investigated the magnetic orderings, crystal lattice distortion
    and spin dynamics in\r\nmagnetocaloric material HoB2, by using neutron diffraction,
    x-ray diffraction experiments and AC\r\nsusceptibility measurements. Although
    HoB2 exhibits the ferromagnetic phase transition at T1=15 K, the other phase transition
    at T2=11 K has not been elucidated so far. In the present high resolution powder
    neutron diffraction and single crystal x-ray diffraction experiments, we observed
    the crystal structure phase transition from hexagonal (P6/mmm) to monoclinic (C2/m)
    at T2. The structure change concomitantly occurs with change in the moment size
    and fixing the spin orientation angle of Ho3+ moments below T2. Analyzing the
    structure distortion mode coupled to spin direction, we found that the ferromagnetically
    ordered moments is in the hexagonal (x, -x, z)-plane. In the AC susceptibility
    measurements, we observed a large enhancement in the susceptibility along the
    ab-plane for T2 < T < T1, indicating that the ferromagnetic state in the intermediate
    temperature region is characterized by large spin fluctuations. "
