Alternative Buffer-Layers for the Growth of SrBi2Ta2O9 on Silicon
J. Schumacher, J. C. Martinez, F. Martin +4
In this work we investigate the influence of the use of YSZ and CeO2/YSZ as insulators for Metal- Ferroelectric-Insulator-Semiconductor (MFIS) structures made with SrBi2Ta2O9 (SBT)…
Ferroelectricity and structure of BaTiO3 grown on YBa2Cu3O7-d thin films
Ch. Schwan, F. Martin, G. Jakob +2
We have investigated the crystal structure and the ferroelectric properties of BaTiO3 thin films with YBa2Cu3O7-d as the bottom and Au as the top electrode. Epitaxial heterostructu…
Hall effect of epitaxial double-perovskite Sr_2FeMoO_6 thin films
W. Westerburg, F. Martin, G. Jakob
We prepared high epitaxial thin films of the compound Sr_2FeMoO_6 with narrow rocking curves by pulsed laser deposition. The diagonal and nondiagonal elements of the resistivity te…
Charge carrier density collapse in La_0.67Ca_0.33MnO_3 and La_0.67Sr_0.33MnO_3 epitaxial thin films
W. Westerburg, F. Martin, G. Jakob +2
We measured the temperature dependence of the linear high field Hall resistivity of La_0.67Ca_0.33MnO_3 (T_C=232K) and La_0.67Sr_0.33MnO_3 (T_C=345K) thin films in the temperature…
Current dependence of grain boundary magnetoresistance in La_0.67Ca_0.33MnO_3 films
W. Westerburg, F. Martin, S. Friedrich +2
We prepared epitaxial ferromagnetic manganite films on bicrystal substrates by pulsed laser ablation. Their low- and high-field magnetoresistance (MR) was measured as a function of…
