Abstract: | Femtosekundové laserové excitace v polokovových sloučeninách (HM) teoreticky předpokládají, že indukují exotickou pikosekundovou spinovou dynamiku. Experimenty s femtosekundovou spinovou dynamikou prováděné na Fe 3 O 4 pomocí fotoelektronové spektroskopie s časovou a spinovou resolutí podporují náš model. Navíc se reakce polarizace spinu ukazuje jako velmi robustní a může být přijata pro selektivní testování objemového charakteru HM v širokém spektru sloučenin. |
Abstract in different language: | Femtosecond laser excitations in half-metal (HM) compounds are theoretically predicted to induce an exotic picosecond spin dynamics. Femtosecond spin dynamics experiments performed on Fe 3 O 4 by time- and spin-resolved photoelectron spectroscopy support our model. Furthermore, the spin polarization response proves to be very robust and it can be adopted to selectively test the bulk HM character in a wide range of compounds. |
