Oxygen Vacancies Driven Photoconductivity in Layered Cobaltite Epitaxial Films

Advanced Electronic Materials, EarlyView.
ABSTRACT Understanding photoinduced phenomena in complex oxides is crucial for developing next‐generation optoelectronic devices. Here, we report pronounced ultraviolet (UV) light‐induced photoconductivity in epitaxial PrBa1‐xCaxCo2O5+δ (x = 0.5) thin films grown on (001) LSAT substrates via pulsed laser deposition.

Emergent Spin Fluctuation and Structural Metastability in Self‐Intercalated Cr1+xTe2${\rm Cr}_{1+x}{\rm Te}_2$ Compounds

Advanced Electronic Materials, EarlyView.
Metastable superstructure and emergent spin fluctuation in self‐intercalated Cr1+xTe2${\rm Cr}_{1+x}{\rm Te}_2$ ABSTRACT Intercalated van der Waals (vdW) magnetic materials host unique magnetic properties due to the interplay of competing interlayer and intralayer exchange couplings, which depend on the intercalant concentration within the van der ...

Lattice-Spin Mechanism in Colossal Magnetoresistive Manganites

Physical Review Letters, 2002
We present a single-orbital double-exchange model, coupled with cooperative phonons (the so called breathing-modes of the oxygen octahedra in manganites). The model is studied with Monte Carlo simulations. For a finite range of doping and coupling constants, a first-order Metal-Insulator phase transition is found, that coincides with the Paramagnetic ...

Machine Learning‐Assisted Second‐Order Perturbation Theory for Chemical Potential Correction Toward Hubbard U Determination

Advanced Intelligent Discovery, EarlyView.
In this work, the Doubao large language model (LLM) is involved in the formula derivation processes for Hubbard U determination regarding the second‐order perturbations of the chemical potential. The core ML tool is optimized for physical domain knowledge, which is not limited to parameter prediction but rather serves as an interactive physical theory ...

Temperature and Field Dependence of Magnetic Domains in La$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$

, 2014
Colossal magnetoresistance and field-induced ferromagnetism are well documented in manganite compounds. Since domain wall resistance contributes to magnetoresistance, data on the temperature and magnetic field dependence of the ferromagnetic domain ...

Twist Engineering of Hybrid 2D van der Waals‐Transition Metal Oxide Membranes

Advanced Physics Research, EarlyView.
The integration of transition metal oxide membranes with 2D van der Waals materials offers exciting opportunities to study new interfacial phenomena. These interactions can create complex moiré patterns that change the materials' properties. Understanding these interactions, influenced by symmetry and distortion, poses significant challenges and ...

Structure, magnetic and transport properties of Ti-substituted La0.7Sr0.3MnO3 [PDF]

, 2005
Ti-substituted perovskites, La0.7Sr0.3Mn1-xTixO3, with x between 0 to 0.20, were investigated by neutron diffraction, magnetization, electric resistivity, and magnetoresistance (MR) measurements. All samples show a rhombohedral structure (space group R3c)
