## Description

- description: 'The successful growth of single crystals of a cubic Laves-phase material
    HoAl2 with the space group Fd-3m is reported. The crystals were grown by a floating-zone
    method with five laser di-odes as a heat source. Al-rich feed rods were prepared
    for compensation of heavy evaporation during the growth. The nominal ratio for
    the feed rods was optimized as Ho : Al = 1 : 2.5. Single crystals of HoAl2 with
    a length of 50 mm were firstly grown in this technique. Obtaining the large-size
    crystal by the floating-zone method enabled us to systematically explore the physical
    properties using the same batch crystal. The crystal possessed a second-ordered
    ferromagnetic transition at 29 K and a first-ordered spin-reorientation transition
    at 20 K. The bulk physical properties such as specific heat, magnetic susceptibility,
    isothermal magnetization, and thermal expansion measurements were measured. Also,
    a magnetocaloric effect was evaluated by the magnetic entropy change. We systematically
    demonstrate that anisotropic physical properties along the principal axes ([100],
    [110], and [111]) emerged below the magnetically ordered states, in contrast to
    the isotropic behavior in the paramagnetic state. '
