We demonstrate the existence of the metal to insulator transition (TMIT) up to 30% of Ru substitution at the Mn site, while the ferromagnetic transition (TC) is sustained even beyond 30% Ru substitution in the pulsed laser deposited La0.7Ca0.3Mn1−xRuxO3 thin films. The presence of Ru(IV) and (V) states complementing the t2g and eg orbital parentage of Mn(III) and Mn(IV) brings about prolonged double exchange mediated magnetic and electronic interactions, as confirmed by the X-ray absorption spectra and a negative magneto resistance ratio (MR) up to 11% at TMIT even for 30% Ru substitution.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
