Antiferromagnetism in CaCu $_{3}$ Ti $_{4}$ O $_{12}$ studied by magnetic Raman spectroscopy

A. Koitzsch, G. Blumberg, A. Gozar +4

For CaCu $_{3}$ Ti $_{4}$ O $_{12}$ -- an insulator that exhibits a giant dielectric response above 100 K -- Cu $^{2 +}$ antiferromagnetic spin ordering has been investigated by magnetic…

Suppression of weak localization effects in low-density metallic 2D holes

A. P. Mills, A. P. Ramirez, X. P. A. Gao +3

We have measured the conductivity in a gated high-mobility GaAs two dimensional hole sample with densities in the range (7-17)x10^9 cm^-2 and at hole temperatures down to 5x10^-3 E…
