Kondo lattice behavior and magnetic field effects in Al20V2Eu Conference Paper

abstract

• Al20V2Eu has a framework identical to the Al10V intermetallic, but with the large structural void filled by Eu. Magnetization results indicate a nearly 2+ Eu valence state, and a magnetic transition near 4 K. Specific heat results exhibit a gradual enhancement of the electronic term , to 340 mJ/mol K at 8 T. In addition, the high-field 27Al NMR T1 exhibits a crossover from local-moment behavior to Korringa-like behavior near 50 K. These results indicate that the low-temperature magnetic state is built from moments affected by Kondo screening, which is enhanced by application of a magnetic field. 2007 Elsevier B.V.
