- Abstract
- We grew highly epitaxial DyMn2O5 (DMO) thin films on Nb-doped TiO2(110) single crystal substrates by using the pulsed laser deposition technique and studied their magnetic properties. The surface normal crystal direction changed from DMO(002) to DMO(211) with increasing growth temperature from 750 A degrees C to 950 A degrees C. Bulk-like magnetic properties were observed for the film grown at 950 A degrees C while behaviors different from the bulk were observed for the film grown at 750 A degrees C. This difference in the magnetic properties is attributed to a structural deformation caused by the strain due to the substrate.
