Description

The studies on the multizone superconductivity in the Mg1-xAlxB2 system are carried out through the tunnel and Andreev spectroscopy. The temperature dependences of the superconducting gaps as well as their changes by growing Al disorder and concentration are studied. It is shown that the experimental dependences cannot be explained in detail within the frames of the currently existing microscopic theories

Abstract (Russian)

Проведены исследования многозонной сверхпроводимости в системе Mg1-xAlxB2 методами туннельной и андреевской спектроскопии. Изучены температурные зависимости сверхпроводящих щелей, а также их изменения при возрастании неупорядоченности и концентрации Al. Показано, что экспериментальные зависимости не могут быть детально объяснены в рамках существующих к настоящему времени микроскопических теорий
