Abstract

The recently derived Landau-Lifshitz-Bloch equation of motion for two-component magnetic systems, including ferri- ferro- and antiferromagnets, provides a framework to analyze species dependent ultra fast demagnetization rates. In agreement with reported experimental observations, we show that Gd sublattice demagnetizes slower then FeCo in GdFeCo. However, we predict that at high initial temperatures Gd should be faster than Fe, providing the possibility to control the polarity of the transient antiferromagnetic state. Our results indicate that typically Fe should be slower than Ni in FeNi. The situation is opposite if Fe is 4 times stronger coupled to the electronic system than Ni.
