  • The rise of three-dimensional topological insulators as an attractive playground for the observation and control of various spin-orbit effects has ushered in the field of topological spintronics. To fully exploit their potential as efficient spin-orbit torque generators, investigating the efficiency of spin injection and transport at various topological insulator/ferromagnet interfaces is crucial. Here, using all-optical time-resolved magneto-optical Kerr effect magnetometry, we demonstrate efficient room-temperature spin pumping in Sub/BiSbTe1.5Se1.5(BSTS)/Co20Fe60B20(CoFeB)/SiO2 thin films characterized by the spin-mixing conductances of the interface and the spin diffusion length in BSTS, and obtain an ultrahigh interfacial spin transparency.

  • Catch bonds exist in some protein-ligand complexes and are of interest for their increased lifetime under greater mechanical force. Here, a mathematical model for nanoparticles tethered with macromolecules shows catch-bond behavior, which may be useful for designing synthetic materials.
