Abstract

The antimony-121 Mössbauer spectra of the Yb14MnSb11 Zintl compound have been obtained between 5 and 300 K. A three-dimensional array of the spectral counts, velocity, and temperature has been simultaneously fit with two components and seven fitted parameters. These fits yield a zero temperature hyperfine field of 2.9(2) T, a Curie temperature of 57(3) K, and a Mössbauer temperature of 182(2) K for Yb14MnSb11.
