Abstract
We report the results of 11B nuclear magnetic resonance (NMR) measurements of SrB6 and Ca0.995La0.005B6 below room temperature. Although the electrical resistivities of these two materials differ substantially, their 11B-NMR responses exhibit some strikingly common features. Both materials exhibit ferromagnetic order, but their 11B-NMR spectra reveal very small hyperfine fields at the boron sites. The spin-lattice relaxation T-11 varies considerably with external field but changes with temperature only below a few K. We discuss these unusual results by considering various different scenarios for the electronic structure of these materials. © 2001 The American Physical Society.
