摘要: We have studied the response of exchange split valence bands ferromagnetic gadolinium tofemtosecond laser excitation. observe a drop splitting with time constant 0.9 ps but different times minority and majority spin bands. Furthermore, even above Curie temperature there is finite splitting, which also decreases
