Epitaxial growth and transport properties of Nb-doped SrTiO$_{3}$ thin films (2005)
Takahashi, K. S., Jaccard, D., Shibuya, K., Ohnishi, T., Lippmaa, M., Triscone, J. -M.
Nb-doped SrTiO$_{3}$ epitaxial thin films have been prepared on (001) SrTiO$_{3}$ substrates using pulsed laser deposition. A high substrate temperature ($>1000^{\circ}{C}$) was found to be necessary...
Scaling of the anomalous Hall effect in Sr$_{1-x}$Ca$_x$RuO$_3$ (2003)
Mathieu, R., Asamitsu, A., Yamada, H., Takahashi, K. S., Kawasaki, M., Fang, Z., ...
The anomalous Hall effect (AHE) of ferromagnetic thin films of Sr$_{1-x}$Ca$_{x}$RuO$_3$ (0 $\leq x \leq$ 0.4) is studied as a function of $x$ and temperature $T$. As $x$ increases, both the...
Anomalous Hall Effect and Magnetic Monopoles in Momentum-Space (2003)
Fang, Z., Nagaosa, N., Takahashi, K. S., Asamitsu, A., Mathieu, R., Ogasawara, T., ...
Efforts to find the magnetic monopole in real space have been made in cosmic rays and in accelerators, but up to now there is no firm evidence for its existence due to the very heavy mass $\sim...
