Experimental evidence for magnetic resonance in the antiferro‐quadrupole phase

Abstract

Abstract For strongly correlated electronic systems in addition to magnetically ordered phases based on the interaction between magnetic dipoles magnetic ordering originating from the quadrupolar magnetic interactions is possible. Up to now any information about magnetic resonances specific to quadrupolar ordering is missing. Here we report experimental evidence of the magnetic resonance in the antiferro‐quadrupole phase of CeB 6 . The temperature dependence of resonance parameters allows concluding about the essential role of the quadrupole ordering in the observed phenomenon. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
