The BME-MTA Magneto-optical Spectroscopy Research Group of the Department of Physics published two experimental studies in Scientific Reports. In their first study [1], they reveal the ferroelectric domain structure of polar magnets, and their effects on the magnetic skyrmions in the material. In their subsequent work [2], they report the first-time observation of an exotic magnetically ordered ground state, a so-called skyrmion lattice.
