Twist Engineering of Hybrid 2D van der Waals‐Transition Metal Oxide Membranes
Advanced Physics Research, Volume 5, Issue 6, June 2026.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 ...

Anomalous magnetic and transport properties of InSb(Mn) crystals near metal-insulator transition
AIP Advances, 2018 In Mn-doped InSb single crystals an unusual, for nonmagnetic semiconductors, dependence on manganese concentration have been revealed for magnetization, conductivity, magnetoresistance and the Hall effect in the range NMn= (1÷2)×1017cm-3.

From colossal magnetoresistance to solar cells: An overview on 66 years of research into perovskites
, 2017 Perovskites are a huge family of compounds to which the natural titanium mineral CaTiO3 is the common ancestor. The cubic structure looks apparently simple, but the variety of metal ions and mixtures thereof that fit into a perovskite lattice is ...

Oxygen Vacancies Driven Photoconductivity in Layered Cobaltite Epitaxial Films
Advanced Electronic Materials, Volume 12, Issue 10, 25 May 2026.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.

Advanced Functional Materials, Volume 36, Issue 28, 7 April 2026.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Critical Nucleation in Colossal Magnetoresistance
, 2003 Critical exponents have been obtained for a 3D spin particle system. Clusters are formed and system reaches a critical behavior when fragment size distribution follows a power law, as predicted by Fisher Liquid Droplet Model. Also, spontaneous magnetization critical temperature is in agreement with other theoretical studies.
