摘要：

The superconductivity in LaPd2Al2-xGax compounds was studied by means of electrical resistivity and specific heat measurements. The concentration development of the superconducting properties was revealed. The measured data deviate significantly from the Bardeen-Cooper-Schrieffer theory predictions and are discussed in the context of unconventional superconductivity. The electronic specific heat below T-SC follows almost quadratic temperature dependence, which might indicate an axial state with line nodes in the superconducting gap structure.
