Crystal and magnetic structure of La1-xSr1+xMnO4 : role of the orbital degree of freedom
Abstract
The crystal and magnetic structure of La1-xSr1+xMnO4 (0<x<0.7) has been studied by diffraction techniques and high resolution capacitance dilatometry. There is no evidence for a structural phase transition like those found in isostructural cuprates or nickelates, but there are significant structural changes induced by the variation of temperature and doping which we attribute to a rearrangement of the orbital occupation.
