摘要：

Raman spectra of SrRuO3 films grown epitaxially on LaAlO3 substrate by a pulsed laser deposition have been measured. Phonon spectra showed an anomalous temperature dependence in the range of the magnetic phase transition indicating strong spin-lattice interaction. No sharp magnon lines were observed, but the broad continuum spectrum showed redistribution of intensity at the magnetic phase transition suggesting that multimagnon processes may contribute to the continuum. © 1995 The American Physical Society.
