Preserved Fulltext
We present results of a time-resolved study of the ultrafast magnetic response of Gd23.1Fe71.9Co5.0 MAMMOS structures under conditions near actual read/write temperatures. An all-optical pump and probe method was used in which an intense (pump) light beam excited a medium due to ultrafast laser heating and a less intense beam monitored this photo-excited state through the magneto-optical Kerr effect. Our experiment clearly demonstrates that the photo-excitation effectively excites coherent spin
