Estudos no sistema pseudoternário CeCoGe(3-x)Six (com 0 = < x = < 3) mostraram que o sistema evolui continuamente de um estado antiferromagnético da rede de Kondo (CeCoGe(3) com ~21k) para um composto de valência intermediária (CeCoSi(3) com Tw ~230k). O sistema apresenta comportamento tipo não- líquido de Fermi (NLF) em torno do ponto crítico quântico (PCQ) na concentração crítica xC = 1,25. A substituição isoeletrônica dos átomos de por não aumenta o grau de desordem magnética, sendo ideal para o estudo de efeitos intrínsecos das variações das constantes de interação da rede Kondo. Estudamos este sistema em concentrações próximas à concentração crítica através de medidas de resistividade elétrica AC sob pressão (x=0,9) e campo magnético (x =1), em amostras policristalinas. Nossos resultados mostram que a ordem magnética de longo alcance presente na amostra CeCoGe(2,1)Si(0,9) é suprimida com o aumento da pressão e, para a pressão crítica PC ( aprox. 6,2 kbar) TN é aproximadamente zero. Para temperaturas inferiores a TN, as medidas de resistividade são bem descritas considerando um espalhamento de elétrons de condução por mágnons antiferromagnéticos anisotrópicos. Acima de PC observa-se o comportamento líquido de Fermi. Na região crítica o estado NLF foi observado. A análise do comportamento da linha crítica na proximidade do PCQ indica que as flutuações magnéticas relevantes são tipicamente bidimensionais. Por outro lado, no composto CeCoGe2Si, que apresenta ordem magnética de curto alcance com TN aproximadamente 2K, observa-se que a temperatura de ordenamento é reduzida com o aumento do campo magnético e, para campos acima de 3 T, surge o comportamento tipo líquido de Fermi.
Studies on the pseudo ternary system CeCoGeSix (where 0 = < x = < ) have shown that the system evolves continuously from a Kondo lattice antiferromagnetic state ( CeCoGe(3) with ) towards a mixed valent compound ( CeCoSi(3)with Tw ~230k ). The system displays a non-Fermi-liquid-type behavior (NFL) in the vicinity of the quantum critical point (QCP) at the critical concentration . Isoelectronic substitution of atoms for does not enhance the degree of magnetic disorder, rendering it ideal for the study of the Kondo lattice¡ s interaction constants intrinsic effects. We have studied this system in polycrystalline samples at concentrations close to the critical one through AC electrical resistivity under pressure (x= 0,9) and magnetic field (x=1) measurements. Our results show that the long range magnetic order present in the CeCoGe(2,1)Si(0,9) sample is suppressed as pressure is increased, and that for the critical pressure PC (aprox. 6,2 kbar), TN (aprox. zero) . For temperatures below TN, the resisitivity data are well described considering conduction electron scattering by anisotropic antiferromagnetic magnons. Above PC we observe the Fermi liquid behavior. At the critical region, a NFL state with exponents close to 1 was found. The analysis of the behavior of the critical line in the neighborhood of the QCP indicates that the relevant magnetic fluctuations are typically two-dimensional. On the other hand, the CeCoGe(2)Si compound displays short range order (TN ~ 2k). The ordering temperature is reduced under an increase of an applied magnetic field, and for magnetic fields above 3 T a Fermi liquid behavior arises.
