  • Unidirectional spin-hall magnetoresistance is a change in the conductivity of ferromagnetic/heavy metal bilayers that is sensitive to the magnetisation of the ferromagnetic layer. This sensitivity makes it a potential candidate for magnetic state readout. Here, Salikhov et al demonstrate ultrafast unidirectional spin hall magnetoresistance driven by terahertz fields

  • Technologies operating in the terahertz (THz) range are essential for advancing high-speed communication, sensing and imaging. Here, the authors demonstrate that a HgTe-based heterostructure with electronic band inversion can efficiently mix and up-convert weak signals into THz frequencies at room temperature, using strong nonlinear effects.

  • Polycrystalline thin films of elemental bismuth exhibit a room-temperature nonlinear transverse voltage due to geometric effects of surface electrons that is tunable and can be extended to efficient high-harmonic generation at terahertz frequencies.

  • Probing the growth and evolution of phase-coexistence in complex materials is key to understanding electronic phase transitions. Here, a combination of THz time-domain spectroscopy and DC transport provides a way to probe coexistence of metallic and insulating clusters in a disorder-controlled metal-insulator transition.
