Summary: This study investigates the synthesis and electronic properties of epitaxial perovskite La1-xSrxRhO3 thin films, revealing the effect of Sr doping on the electronic phase diagram. Experimental data show an insulator-metal-insulator transition caused by Sr addition, which is explained by theoretical calculations.

Summary: This study demonstrates a genuine Mott transition without any symmetry breaking side effects in thin films of V2O3 using material synthesis and photoelectron spectroscopy. The spectral signal evolves slowly over a wide temperature range approaching the metal-insulator transition, with the Fermi wave-vector remaining unchanged and a lower critical temperature than that reported for the bulk.

Summary: This paper investigates the characteristics of low-energy magnetic excitations in the manganese oxide material La0.7Ca0.3MnO3. The results show that at 300K, the magnetic excitations consist of a diffusive ferromagnetic component at the Brillouin zone center and a quasielastic excitation at the Brillouin zone edge, both of which exhibit weakened intensity at 215K.

Summary: Disorder induced phase slip events were observed in current voltage characteristics of two-dimensional TiN thin films produced through robust substrate mediated nitridation technique. The critical temperature and resistive steps in the characteristics were found to vary strongly with annealing temperature and thickness, indicating the robustness of the synthesis process in fabricating disordered nitride-based superconductor.

Summary: The transition from ferromagnetic half-metal to ferromagnetic insulator in SrVO3/SrTiO3 superlattices can be achieved by adjusting the number of SrTiO3 layers. Ti-V mixed defects play a crucial role in this metal-insulator transition.

Summary: We propose a model to estimate the energy barrier responsible for the hysteresis of the thermally driven Mott phase transition and validate the model with experimental data. For heating, the resistance in VO2 films exhibits step-like changes, forming multiple nonvolatile states, while no significant changes occur during cooling. The memory ability is attributed to the structure of the metal and insulator domains.

Summary: The study investigates the relationship between the properties of Gd0.1Ca0.9MnO3 thin films and their thickness, revealing a sudden change in electrical transport properties and an insulator-to-metal transition when film thickness exceeds 80 nanometers. This transition coincides with the appearance of a ferromagnetic phase in thicker samples.

Summary: The effects of strain on the metal-insulator phase transitions in V2O3 are explored. It is found that the expansion of the ab-plane is crucial for inducing negative pressure effects in the films. The findings provide insights into manipulating a Mott transition in V2O3 and expanding its potential applications in electronics.

Summary: We demonstrate room-temperature spin injection using spin pumping in a BiSb/(Ga,Fe)Sb heterostructure, where (Ga,Fe)Sb is a ferromagnetic semiconductor with high Curie temperature and BiSb is a topological insulator. Despite the small magnetization of (Ga,Fe)Sb at room temperature, we detected spin injection from (Ga,Fe)Sb by utilizing the large inverse spin Hall effect in BiSb. This study provides the first demonstration of room-temperature spin injection from a ferromagnetic semiconductor.

Summary: This work investigates the phase transition of a highly disordered amorphous VO2 film and finds that its electronic transport behavior is influenced by the film's thickness, showing different thermal sensitivity. The study also introduces the concept of a prototype device with overheating protection capability, providing a unique pathway to understand the metal-insulator transition in strongly correlated electronic systems and its functionality in electronic devices.

Summary: The ability to manipulate spins in magnetic materials is crucial in spintronics device design. This study demonstrates the tunable magnetic properties of TbFeCo on VO2/TiO2 films using strain-induced effects. Through anomalous Hall effect measurements, it is confirmed that the metal-insulator transition of VO2 can alter the magnetic anisotropy and magnetization of TbFeCo. This research lays the foundation for controlling magnetic properties through phase transitions.

Summary: Local moment formation is observed in disordered semiconductors, and it arises from short-ranged, repulsive electron-electron interactions. In this study, paradigmatic models of interacting insulators are used to investigate the behavior of local moments. The results show exponential decay of charge and fermion correlations, while spin correlations exhibit power-law decay, indicating the presence of a random singlet phase.

Summary: Local moment formation is commonly observed in disordered insulators due to short-range, repulsive electron-electron interactions. By studying one-dimensional Hubbard chains with quenched randomness, we find exponential decay of charge and fermion two-point correlations, but power-law decay of spin correlations.

Summary: The study found that oxygen vacancies rapidly alter the electronic configuration within the Ni and O orbital manifolds, but in RENiO3-x, antiferromagnetic order is remarkably robust to substantial levels of carrier doping, up to 0.21 e(-) /Ni. The sudden collapse of ordered magnetism upon oxygen removal may provide a new mechanism for solid-state magnetoionic switching.
