Beschreibungen/Notizen

• Crack-free K(Sr 0.5 Ba 0.5 ) 2 Nb 5 O 15 (KSBN50) thin films could successfully be prepared by the control of the reactions through the sol-gel method. KSBN50 precursor powder was directly crystallized to the tetragonal tungsten bronze phase without formation of low temperature phase at 600°C. KSBNSO thin films on MgO(100) and Pt(100)/MgO(100) also crystallized to the tetragonal tungsten bronze with c-axis highly orientation at 600°C. Two crystal lattice planes of KSBN50 were intergrown at an orientation of 18.5 degrees on MgO(100) substrate. The Curie point of KSBN50 thin films was at around 60°C at 10 kHz. KSBN50 thin films on Pt(100)/MgO(100) substrates exhibited the typical P-E hysteresis.
