Abstract

Read online

Using ultrashort laser pulses it is possible to induce ferromagnetic ordering in otherwise anti-ferromagnetic FeRh. Here, Li et al. use THz emission spectroscopy with double pump to probe the transient dynamics of this transition, showing the insusceptibility of the ferromagnetic order to applied magnetic fields at picosecond timescales.
