Thermodynamic and electrical transport properties of CeRhSb1-xTe x systems: Transition from Kondo insulating to the Griffiths and non-Fermi liquid states

It follows from our analysis of CeRhSb that the formation of Kondo insulator state due to the presence ofthe collective spin singlet state is strongly reduced by its doping with various dopants when their amountexceeds 8%-10%, regardless of whether they are substitute Ce, Rh or Sb. A wide variety of experimentalresults (electrical resistivity, magnetic susceptibility, specific heat, x-ray photoelectron spectroscopy)and theoretical investigations have convincingly demonstrated the proposed earlier scaling lawx=.inthe Kondo insulator regime, which is universal for all known Kondo insulators. We also analyze the propertiesof the Griffiths phase for CeRhSb when Pd substitutes Rh, or Sb is fractionally replaced by Te or Sn, whereasdoping of Ce with La leads to the formation of magnetic cluster structure as a result of the Kondo hole effect.Magnetoresistance of CeRhSb as a function of the fieldshows a negative2behavior, which is characteristicof the Kondo-lattice systems, it is also documented for various topological materials. Electrical resistivity of CeRhSb, as well as of CeRhSb1-Te(<= 0.6) and CeRh1-PdSb (<= 0.04), follows=(0)-law between 0.4 and similar to 2.5K, which suggests a non-Fermi liquid-like behavior due to presence of the Griffiths phase.
