In this thesis, we prepared pure (001)-oriented h-YMnO3 thin films on (100)MgO, (111)MgO and (111)YSZ substrates by pulsed laser deposition(PLD), respectively. And we get the crystal structure and strain effect of these thin films by X-ray diffraction and phi-scan. In further, we will show the results of the ultrafast dynamics in these samples probed by the tunable wavelength optical pump-optical probe technique. Especially, the influence of epitaxial strain due to lattice mismatch between the substrate and h-YMO films on the magnitude of Edd and Néel temperature (TN).
