Strain-enhanced Dzyaloshinskii-Moriya interaction at Co/Pt interfaces.

Abstract：

:The interfacial Dzyaloshinskii-Moriya interaction (DMI) is an essential ingredient for stabilizing chiral spin configurations in spintronic applications. Here, via first-principles calculations, we reveal the influence of lattice strain on DMI in Co/Pt interface. We observed a considerable enhancement for a certain lattice strain. Furthermore, a direct correlation is established between the DMI and interlayer distances dominated by the strain, which is attributed to a hybridization of electronic orbitals. This hybridization has also been presented as the microscopic origin of the interfacial DMI. We anticipate that our predictions provide new insights into the control of interfacial DMI for skyrmion-based spintronic devices.

  • Occurrence of randomly recombined functional 16S rRNA genes in Thermus thermophilus suggests genetic interoperability and promiscuity of bacterial 16S rRNAs.

    abstract：:Based on the structural complexity of ribosomes, 16S rRNA genes are considered species-specific and hence used for bacterial phylogenetic analysis. However, a growing number of reports suggest the occurrence of horizontal gene transfer, raising genealogical questions. Here we show the genetic interoperability and prom...
