Diluting the Kondo lattice CeCoIn5 reveals two distinct energy scales. This Kondo lattice study shows antiferromagnetic correlations influence magnetic moment screening, differing from single-impurity Kondo behavior.

Area of Science:

  • Condensed matter physics
  • Quantum magnetism
  • Materials science

Background:

  • The Kondo lattice system CeCoIn5 exhibits complex magnetic properties.
  • Understanding the interplay between single-impurity and lattice effects is crucial.

Purpose of the Study:

  • To investigate the effects of La dilution on the Kondo lattice CeCoIn5.
  • To identify and characterize the different energy scales governing its magnetic behavior.

Main Methods:

  • Studying magnetic susceptibility and specific heat scaling laws.
  • Analyzing Ce-dilute alloys and dense Kondo regimes.

Main Results:

  • Two distinct energy scales were identified: single-impurity Kondo temperature T(K) and intersite spin-liquid temperature T(*).

Related Experiment Videos

  • Ce-dilute alloys showed a Fermi liquid ground state.
  • Dense Kondo regimes exhibited non-Fermi-liquid behavior in specific heat and resistivity, scaling with T(*).

    • Conclusions:

    • The screening of magnetic moments in the lattice involves antiferromagnetic intersite correlations.
    • These intersite correlations operate on a larger energy scale than in the Kondo impurity case.
