Description

We have studied the electrical resistivity of YbCo2Zn20 under magnetic field up to 18 T. With applying magnetic field, the contribution of the Kondo interaction to the electrical resistivity is suppressed and the Fermi liquid regime is extended to higher temperature range. Both the T2 coefficient of the electrical resistivity A and the residual resistivity ρ0 strongly decrease in magnetic field. From the magnetic variation of the resistivity, it has been found that YbCo2Zn20 is classified as a heavy fermion system with small Kondo temperature of ∼ 1.0K.
