3, a well-known room temperature multiferroic, the competition between various exchange interactions manifests itself as non-collinear spin order, i.e., an incommensurate spin cycloid with period 64nm. We report on the stability and systematic expansion of the length of the spin cycloid in (110)-oriented epitaxial Co-doped BiFeO 3 thin ﬁlms. My Research Activities. My research is primarily focused on the design, fabrication, and characterization of oxide thin film functional materials (most notably multiferroics) which can be used in applications such as non-volatile memory elements, magnetic, spintronic, or optical devices and modulators. The research emphasis is on gaining a.

Here we report the retention of the spin cycloid in 100 nm thin films of BFO, grown on (110)-oriented SrTiO 3 (STO) substrates with a SrRuO 3 (SRO) bottom electrode. This lifts the previously considered geometrical constraint that the spin cycloid collapses in thin films thinner than ~300 nm grown on STO substrate 23, 24, 28..

After the spin-coating process, the sample was pre-annealed at 200 °C for 5 min to eliminate the organics, then annealed at 550 °C in N2 ambient for 1 h to obtain the perfect film. The BFO and mixed NTO-BFO thin films (~100 nm) were deposited on the SRO bottom electrode through a spin-coating process, pre-annealed at 200 °C for 10 min. BiFeO 3 has a G-type antiferromagnetic modulated cycloid spin structure along [1 1 0] h, with a long wavelength of ∼640 Å, which leads to zero macroscale magnetization.

For sample deposition, we used RF sputtering of BFO stoichiometric sintered targets at pure-oxygen plasma pressure of 1.0 × 10 −1 mbar, with a RF power of 90 W and substrate temperature of 600 °C. No annealing process was required before cool down to room temperature. Deposition rate was 0.1 Å/s and film thickness was kept at 120 nm. BiFeO 3 (BFO) is the most widely studied multiferroic material, due to its above room temperature antiferromagnetism (T N ~ 640 K) and ferroelectricity (T CFE ~ 1100 K) 1.BFO has G-type antiferromagnetic (AF) spin structure with spin canting and superimposed cycloidal modulation 2, and various magnetic anomalies observed at low temperature 3,4.Ion substitution is a widely adopted strategy.
