Two different relaxation processes are identified. The behavior of the slower process, which is strongly sensitive to the magneto-structural transition, is analyzed in the framework of the relaxation-bottleneck model involving magnons. The results are compared to recent time resolved angular photoemission results (TR-ARPES) and possible alternative assignment of the slower relaxation to th","authors_text":"2), (2) Institute of Physics, (3) Department of Physics, (4) Geballe Laboratory for Advanced Materials, A.
