Elastic Softening Due to Crystal Electric Field Effect in TmB12

Elastic Softening Due to Crystal Electric Field Effect in TmB12

The elastic moduli C44 and (C11-C12)/2 have been measured for rare earth dodecaboride TmB12. With decreasing temperature, both moduli show characteristic softening due to a crystal electric field effect. We have determined a 4f-electronic level scheme by an analysis using a strain-quadrupole interac...

Zusammenfassung:The elastic moduli C44 and (C11-C12)/2 have been measured for rare earth dodecaboride TmB12. With decreasing temperature, both moduli show characteristic softening due to a crystal electric field effect. We have determined a 4f-electronic level scheme by an analysis using a strain-quadrupole interaction theory.
