Die elektrischen Eigenschaften des Kondo-Supraleiters (La, Ce)Al2

Abstract: The Electrical Properties of the Kondo-Superconductor L(_L_ ~, Ce)A12In the ternary alloy (La, Ce)A12 the Kondo anomalies due to the Cerium impurities are studied in the normal and superconducting state. A vanishing of superconductivity in certain (La, Ce)A12 alloys below a second transition temperature has been observed for the narrow range of 0.6-0.7 at% Ce-additions. The transition back into the norreal state has been observed by means of dc-conductivity and low frequency mutual inductance measurements down… Show more

“…Among these the Kondo superconductor (La, Ce)Al, was of special interest, because on this system the striking phenomenon of re-entrant superconductivity was established experimentally for the first time [l, 21. Meanwhile a large number of low-temperature anomalies has been observed in the normal state on (La, Ce)Al,: in the resistivity [3], magnetoresistance [4], susceptibility [5], specific heat [6J, and thermoelectric power [TI.…”

“…Entre las características más interesantes exhibidas por los superconductores Kondo se encuentran la rápida supresión de la T c en función de la concentración de impurezas (La 1−x Gd x , La 3−x Gd x y La 1−x Gd x Al 2 [12,114,115]), superconductividad sin brecha de energía (películas delgadas de In 1−x Fe x [116]) y superconductividad reentrante (La 1−x Ce x , La 1−x Ce x Al 2 y La 1−x Th x Ce [13,15,68,[70][71][72]).…”

“…Ambos métodos de medición muestran la transición superconductora a T c1 = 1,2 K y el retorno al estado de conducción normal alrededor de T c2 = 0,15 K. b) Resistividad eléctrica específica en función del log(T) para el caso sin campo (superconductor reentrante) y la influencia del campo aplicado en las dos transiciones; Metal normal-Superconductor y Superconductor-Metal normal. La aparición de la segunda temperatura crítica T c2 es causada por el aumento de la refracción del par en el intervalo de temperatura 1-0.2 K. [70].
