By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on General Science. According to news originating from Argonne, Illinois, by NewsRx correspondents, research stated, "The interplay between antagonistic superconductivity and ferromagnetism has been a interesting playground to explore the interaction between competing ground states. Although this effect in systems of conventional superconductors is better understood, the framework of the proximity effect at complex-oxide-based superconductor/ferromagnet interfaces is not so clear."
Our news journalists obtained a quote from the research from Argonne National Laboratory, "The main difficulty originates from the lack of experimental tools capable of probing the interfaces directly with high spatial resolution. Here we harness cross-sectional scanning tunnelling microscopy and spectroscopy together with atomic-resolution electron microscopy to understand the buried interfaces between cuprate and manganite layers. The results show that the fundamental length scale of the electronic evolution between YBa2Cu3O7-delta (YBCO) and La2/3Ca1/3MnO3 (LCMO) is confined to the subnanometre range."
According to the news editors, the research concluded: "Our findings provide a complete and direct microscopic picture of the electronic transition across the YBCO/LCMO interfaces, which is an important step towards understanding the competition between ferromagnetism and superconductivity in complex-oxide heterostructures."
