Abstract
Ultrashort laser pulses are used to induce changes of the magnetization in ferrimagnetic CoxTb1-xalloys. Ultrafast magnetization dynamics has been probed by tr-XMCD at the CoL3and TbM5edges. We demonstrated that demagnetization of the 4f magnetic moment is much faster than in pure Tb when the excited- state-temperature is below the compensation temperature.
