dc.description.abstractPerovskite manganites exhibit fascinating transport and magnetic properties, essential for fundamental research and applications. With the development of thin film technologies, more exotic properties have been observed in doped-manganites over a wide range of temperature. Unraveling the interplay of spin, charge and orbital degrees of freedom that drives exotic, macroscopic properties is therefore crucial for the understanding of strongly correlated electron systems. Here, using a combination of transport, spectroscopic ellipsometry, X-ray absorption spectroscopy and X-ray magnetic circular dichroism, we observe two concomitant electronic and magnetic phases (insulating paramagnetic phase for T>195 K and insulating canted-ferromagnetic for T<140 K) with an intermediate metal-like state in ultra-thin La0.7Sr0.3MnO3 (LSMO) film on DyScO3 substrate. Surprisingly, the O2p-Mn3d hybridization strength reduces with decreasing temperature, driving the system more insulating and ferromagnetic. The Jahn–Teller effect weakens markedly within the intermediate temperature range, making the system more metal-like. We also apply this comprehensive method to a LSMO film on SrTiO3 substrate for comparison. Our study reveals that the interplay of the O2p-Mn3d hybridization and the dynamic Jahn–Teller splitting controls the macroscopic transport and magnetic properties in ultra-thin manganites.en
