After heating by a pump pulse, the film temperature decays exponentially, indicating that the heat flow out of the film is limited by the film/substrate interface. We show that this behavior is consistent with an effective boundary resistance resulting from disequilibrium between the spin and phonon temperatures in the film. © 2010 The American Physical Society.}, year = {2010}, journal = {Physical Review B - Condensed Matter and Materials Physics}, volume = {82}, number = {5}, issn = {10980121}, doi = {10.1103/PhysRevB.82.054425}, note = {cited By 6}, language = {eng}, }
