Abstract The interfacial enhanced ferromagnetism in maganite/ruthenate system is regarded as a promising path to broaden the potential of oxide-based electronic device applications. Here, we systematically studied the physical properties of LaLa1-xCaxMnO3/SrRuO3 superlattices and compared them with the LaLa1-xCaxMnO3 thin films and bulk compounds. The LaLa1-xCaxMnO3/SrRuO3 superlattices exhibit significant enhancement of Curie temperature (TC) beyond the corresponding thin films and bulks. Based on these results, we constructed an extended phase diagram of LaLa1-xCaxMnO3 under interfacial engineering. We considered the interfacial charge transfer and structural proximity effects as the origin of the interface-induced high TC. The structural characterizations revealed a pronounced increase of B-O-B bond angle, which could be the main driving force for the high TC in the superlattices. Our work inspires a deeper understanding of the collective effects of interfacial charge transfer and structural proximity on the physical properties of oxide heterostructures.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
