Abstract

The temperature dependence of the magnetization in two new compounds is presented and compared with Ca₁₄MnBi₁₁. One of the new compounds, Sr₁₄MnBi₁₁, orders ferromagnetically and the other, Ba₁₄MnBi₁₁, is an antiferromagnet at low T. The Curie-Weiss constants C and Θ, found above the ordering temperatures, imply that Mn has four unpaired electrons in each compound and that the near neighbor magnetic coupling in each compound is ferromagnetic, even for antiferromagnetic Ba₁₄MnBi₁₁. For each of these compounds the low temperature high field moment is consistent with the Mn having about 2.5 unpaired electrons.
