Room temperature hydrogenation process and its effect on the magnetic properties of overdoped La1-xSrxMnO3.
The modification of thin films and interfaces through hydrogenation is a flourishing field of research that has shown broad possibilities in tuning the physical properties of different systems. Much research recently has been conducted on correlated oxides, where hydrogen induced reversible metal-to-insulator transitions have been uncovered in different systems, such as as rare earth nickelates [1] and manganites. Regarding manganites, the majority of research focused on optimally doped LSMO(x=0.33) [2,3], and have shown a reduced average Mn oxidation state after hydrogenation, which affects the double-exchange interactions and the related ferromagnetism. This reduction mechanism is the equivalent to that of electron doping [4]. By starting from an overdoped Sr-concentration we hence expect to be able to switch across different magnetic phases, from AF to FM, by hydrogen exposure. The aim of the proposed experiment is two-fold: tracking depth dependent magnetic profiles during in situ H exposure, while simultaneously studying the induced structural modifications of LSMO films at room temperature, which have not yet been studied.
