| Popis: | Nuclear quadrupole resonance (NQR) measurements were performed on the heavy-fermion superconductor ${\mathrm{Ce}}_{3}{\mathrm{PtIn}}_{11}$ with ${T}_{\mathrm{c}}=0.32\phantom{\rule{0.28em}{0ex}}\mathrm{K}$. The temperature dependence of both spin-lattice relaxation rate $1/{T}_{1}$ and NQR spectra evidences the occurrence of two successive magnetic transitions with ${T}_{\mathrm{N}1}\ensuremath{\simeq}2.2\phantom{\rule{0.28em}{0ex}}\mathrm{K}$ and ${T}_{\mathrm{N}2}\ensuremath{\simeq}2.0\phantom{\rule{0.28em}{0ex}}\mathrm{K}$. In successive magnetic transitions, even though the magnetic moment at the Ce(2) site plays a major role, the magnetic moment at the Ce(1) site also contributes to some extent. While a commensurate antiferromagnetic ordered state appears for ${T}_{\mathrm{N}2}lTl{T}_{\mathrm{N}1}$, a partially incommensurate antiferromagnetic ordered state is suggested for $Tl{T}_{\mathrm{N}2}$. |
