Influence of external magnetic field on the reentrant spin-glass state ofAu0.832Fe0.168alloy

${}_{}{}^{57}{}_{}{}^{}\mathrm{Fe}$ Mössbauer-effect studies of the reentrant spin-glass (RSG) state of ${\mathrm{Au}}_{0.832}$ ${\mathrm{Fe}}_{0.168}$ have been performed in the temperature range 4.2≤T≤80 K in external magnetic fields ${\mathit{B}}_{\mathrm{ex}}$ up to 3 T. A detailed analysis of the Mössbauer spectra within the framework of the so-called canting model for the RSG state is presented. Neither a change of the reentrance temperature ${\mathit{T}}_{\mathit{f}}$ nor of the canting angle is observed. This result is compared with a mean-field-theory prediction on ${\mathit{T}}_{\mathit{f}}$(${\mathit{B}}_{\mathrm{ex}}$) and experimental data in other RSG systems.
