Electrical resistivity of the Kondo lattice

Kondo Engineering : from Single Kondo Impurity to the Kondo Lattice

In the first step, experiments on a single cerium or ytterbium Kondo impurity reveal the importance of the Kondo temperature by comparison to other type of couplings like the hyperfine interaction, the crystal field and the intersite coupling. The extension to a lattice is discussed. Emphasis is given on the fact that the occupation number n f of the trivalent configuration may be the implicit ...

Role of volume versus defects in the electrical resistivity of lattice-distorted V(001) ultrathin films

4 nm thick V layers grown by triode sputtering on MgO 001 single crystals and capped with MgO exhibit a perfect epitaxy accompanied by a tetragonal distortion and an unexpected volume compression that increases with the V deposition temperature. The electrical resistivity follows a deposition temperature dependence with these structural modifications, decreasing by an order of magnitude across ...

Effect of exchange bias on the electrical resistivity of Pd doped NiMn thin films: Two-channel Kondo system

Electrical resistivity measurements have been carried out for both flash-evaporated reentrant spin glasses RSGs Ni76−xPdx Mn24 and Ni74.5Mn23.5Pd2, as well as Ni75Mn23Pd2, a pure SG. These measurements were carried out at temperatures down to 4 K. We observed a very deep resistivity minimum at about 75 K for Ni74Mn24Pd2. It was found previously Öner et al., J. Appl. Phys. 89, 7044 2001 that thi...

Antiferromagnetic Kondo lattice compound CePt3P

A new ternary platinum phosphide CePt3P was synthesized and characterized by means of magnetic, thermodynamic and transport measurements. The compound crystallizes in an antiperovskite tetragonal structure similar to that in the canonical family of platinum-based superconductors APt3P (A = Sr, Ca, La) and closely related to the noncentrosymmetric heavy fermion superconductor CePt3Si. In contras...
