Control of thermal gradient using thermoelectric coolers for study of thermal effects

J. of Appl. Phys. 117, 17C508 (2015).
Thermal current is not easy to control,
very different from electric current.
Using TECs, in this paper we show that,
- Seebeck and Nernst effect are often mixed due to unexpect theraml gradient.
- Seebeck and Nernst effect can be sepaarted using their properties.
- Anomalous Nernst effect in Pt/Ni and Pt/Co are measured.
Effect of three dimensional interface in determination of spin polarization using Andreev reflection spectroscopy
J. A. Gifford,a) C. N. Snider, J. Martinez, and T. Y. Chen
Point contacts are not perfectly 1D, what are the effects of a 3D point contact?, In this paper, we show that,
- Point angle affects Andreev spectrscopy
- Can be attributed to Z factor
- Spin polarization can still be determined
- Superconducting gap can still be determined
- No effect for perfect interface with Z=0
