Tailoring surface phase transition and magnetic behaviors in BiFeO3 via doping engineering

Tailoring surface phase transition and magnetic behaviors in BiFeO3 via doping engineering

The charge-spin interactions in multiferroic materials (e.g., BiFeO3) have attracted enormous attention due to their high potential for next generation information electronics. However, the weak and deficient manipulation of charge-spin coupling notoriously limits their commercial applications. To tailor the spontaneous charge and the spin orientation synergistically in BiFeO3 (BFO), in this re...

Strain-induced isosymmetric phase transition in BiFeO3

We calculate the effect of epitaxial strain on the structure and properties of multiferroic bismuth ferrite, BiFeO3, using first-principles density-functional theory. We investigate epitaxial strain corresponding to an 001 -oriented substrate and find that, while small strain causes only quantitative changes in behavior from the bulk material, compressive strains of greater than 4% induce an is...

Tailoring phase slip events through magnetic doping in superconductor-ferromagnet composite films

The interplay between superconductivity (SC) and ferromagnetism (FM) when embedded together has attracted unprecedented research interest due to very rare coexistence of these two phenomena. The focus has been mainly put into the proximity induced effects like, coexistence of magnetism and superconductivity, higher critical current, triplet superconductivity etc. However, very little attention ...

Doping BiFeO3: approaches and enhanced functionality.

BiFeO(3) is one of the most studied multiferroic materials. Both its magnetic and ferroelectric properties can be influenced by doping. A large body of work on the doped material has been presented in the past couple of years. In this paper we provide a perspective on general doping concepts and their impact on the material's functionality.
