Abstract

We report the results of 153Eu and 11B nuclear magnetic resonance (NMR) studies of EuB6 at temperatures above 0.04 K and in magnetic fields between 0 and 7 T. We have observed a surprising evolution of the 153Eu NMR spectrum at very low temperatures, which we interpret as evidence for a complex electronic ground state of EuB6, involving the coexistence of two magnetically very similar, but electronically inequivalent, phases. The low temperature 11B NMR spectra reveal two inequivalent boron sites with internal fields of -0.02 and -0.35T. © 1998 The American Physical Society.
