摘要: The influence of spin-orbit coupling on the transport and magnetic properties ${\mathrm{Co}}_{3}$${\mathrm{Pd}}_{97}$ is investigated. Analysis detailed field- temperature-dependent ac susceptibility data yields a ferromagnetic ordering temperature ${\mathit{T}}_{\mathit{C}}$\ensuremath{\simeq}137 K, although asymptotic critical exponents describing this transition cannot be evaluated due to presence coupling. This estimate for ${\mathit{T}}_{\mathit{C}}$ in excellent agreement with that deduced from derivative zero-field resistivity, dependence coercive field, low-field magnetoresistive anisotropy. occurrence latter anisotropy relies interaction (with an associated orbital moment), behavior anistropy compared model calculations which incorporate
