- W2054242560 abstract "The crystal and magnetic structures of Laves-phase compound $({mathrm{Nd}}_{0.5}{mathrm{Tb}}_{0.5}){mathrm{Co}}_{2}$ have been investigated by high resolution neutron powder diffraction at different temperatures. Magnetization measurement and neutron diffraction reveal two magnetic transitions at ${T}_{mathrm{C}}ensuremath{approx}173phantom{rule{0.3em}{0ex}}mathrm{K}$ and ${T}_{mathrm{M}}ensuremath{approx}47phantom{rule{0.3em}{0ex}}mathrm{K}$, respectively. At room temperature, the compound crystallizes in the $mathrm{Mg}{mathrm{Cu}}_{2}$-type (C15) structure. Below ${T}_{mathrm{C}}$, rhombohedral distortion and large anisotropic magnetostriction take place and persist down to $4phantom{rule{0.3em}{0ex}}mathrm{K}$. In contrast to the binary rare earth $(R)text{ensuremath{-}}mathrm{Co}$ Laves-phases $R{mathrm{Co}}_{2}$, a noncollinear magnetic structure (canted) is deduced for $({mathrm{Nd}}_{0.5}{mathrm{Tb}}_{0.5}){mathrm{Co}}_{2}$, based on the Rietveld refinement of the neutron diffraction data at $50phantom{rule{0.3em}{0ex}}mathrm{K}$ and $4phantom{rule{0.3em}{0ex}}mathrm{K}$. In addition, the correlation between lattice distortion and easy magnetization direction (EMD) commonly observed for binary $R{mathrm{Co}}_{2}$ is violated in $({mathrm{Nd}}_{0.5}{mathrm{Tb}}_{0.5}){mathrm{Co}}_{2}$. Though the crystal structure remains rhombohedral, the EMD of the $R$ sublattice is close to the [110] direction at $50phantom{rule{0.3em}{0ex}}mathrm{K}$ of the pseudocubic lattice and along the [111] direction at $4phantom{rule{0.3em}{0ex}}mathrm{K}$, respectively. The difference of the canting angle between the magnetic structures at $50phantom{rule{0.3em}{0ex}}mathrm{K}$ and $4phantom{rule{0.3em}{0ex}}mathrm{K}$ is small, indicating stable canted configurations. The lattice parameters exhibit a discontinuity around ${T}_{mathrm{M}}$, suggesting a first-order transition between the two canted magnetic structures. The dilution of magnetic anisotropy of the $R$ sublattice and the contribution of the magnetic anisotropy of the Co sublattice are responsible for the observations." @default.
