All-oxide-based synthetic antiferromagnets exhibiting layer-resolved magnetization reversal
Science 357(6347), 191-194 (2017) [10.1126/science.aak9717]
ddc:500
Synthesizing antiferromagnets with correlated oxides has been challenging, owing partly to the markedly degraded ferromagnetism of the magnetic layer at nanoscale thicknesses. Here we report on the engineering of an antiferromagnetic interlayer exchange coupling (AF-IEC) between ultrathin but ferromagnetic La2/3Ca1/3MnO3 layers across an insulating CaRu1/2Ti1/2O3 spacer.

Direct observation of spin excitation anisotropy in the paramagnetic orthorhombic state of BaFe 2 − x Ni x As 2
ddc:530
We use transport and inelastic neutron-scattering measurements to investigate single crystals of iron pnictide BaFe2−xNixAs2(x=0,0.03), which exhibit a tetragonal-to-orthorhombic structural transition at Ts and stripe antiferromagnetic order at TN(Ts≥TN). Using a tunable uniaxial pressure device, we detwin the crystals and study their transport and spin excitation properties at antiferromagnetic wave-vector S1(1,0) and its 90∘ rotated wave-vector S2(0,1) under different pressure conditions.

Visualization of electrolyte filling process and influence of vacuum during filling for hard case prismatic lithium ion cells by neutron imaging to optimize the production process
ddc:620
The process of filling electrolyte into lithium ion cells is time consuming and critical to the overall battery quality. However, this process is not well understood. [...]

Effect of PCBM additive on morphology and optoelectronic properties of P3HT- b -PS films
ddc:540
Thin blend films of the diblock copolymer poly(3-hexylthiophene-2,5-diyl)-block-polystyrene (P3HT-b-PS) and phenyl-C61-butyric acid methyl ester (PCBM) are prepared and investigated. The morphology of films with 9, 25, 33, 50, 58 and 67% PCBM weight fraction is determined. [...]
