Superconducting Properties of the Titanium-Based Oxides Compounds: A Review

Abstract

In recent years, the superconductivity of novel layered materials, titanium-based pnictide oxides, was discovered. Due to the properties of possessing both cuprate and iron-based superconductors, these compounds have attracted the interest of researchers. Titanium pnictide oxides were reported to have CDW or SDW anomalies, theoretical calculations indicate that this DW behavior originates from the Ti2O layer. These compounds which have Ti2O layers provide a basis for studying the relationship between superconductivity and DW behavior. Superconductivity and DW behavior are two different electronic behaviors that typically compete with each other, but sometimes coexist. The relationship between them has always been a focus of condensed matter physics research. Through in-depth research on titanium-based superconductors, it may help us explain the unconventional superconducting transition phenomena present in iron-based superconductors. In this review, we introduce the latest research on titanium pnictide oxides and the electronic properties of these novel superconductors.
