Description

The Fourier transform of the observed magnetic quantum oscillations (MQO) in YBaCuO high-temperature superconductors has a prominent low-frequency peak with two smaller neighbouring peaks. The separation and even the position of these three peaks is almost independent of doping. This pattern has been explained previously by rather special, exquisitely detailed, Fermi-surface reconstruction. We propose that these MQO have a different origin, and their frequencies are related to electron hopping between bilayers and between bilayers rather than directly to the areas of tiny Fermi-surface pockets

Abstract (Russian)

Фурье-образ наблюдаемых магнитных квантовых осцилляций (МКО) в высокотемпературных сверхпроводниках YBaCuO имеет резкий низкочастотный пик с двумя меньшими соседними пиками. Разделение и даже положение этих трех пиков практически не зависит от легирования. Этот набор частот был ранее объяснен довольно специфической перестройкой поверхности Ферми. Мы предполагаем, что эти МКО имеют другое происхождение, и их частоты связаны с перескоком электронов между слоями и между бислоями, а не непосредственно с площадью крошечных карманов поверхности Ферми
