Charge ordering and magneto-polarons in Na $_{0.82}$ CoO $_{2}$

C. Bernhard, A. V. Boris, N. N. Kovaleva +6

Using spectral ellipsometry, we have measured the dielectric function of a Na $_{0.82 (2)}$ CoO $_{2}$ crystal that exhibits bulk antiferromagnetism with T $_{N}$ =19.8 K. We identify two…

Magnetism, Charge Order and Giant Magnetoresistance in SrFeO $_{3 - δ}$ Single Crystals

A. Lebon, P. Adler, C. Bernhard +6

The electronic and magnetic properties of SrFeO $_{3 - δ}$ single crystals with controlled oxygen content ( $0 \leq δ \leq 0.19$ ) have been studied systematically by susceptibility, tra…

Anomalous oxygen isotope effect on the in-plane FIR conductivity of detwinned YBa2Cu3 $^{16, 18}$ O $_{6.9}$

C. Bernhard, T. Holden, A. V. Boris +6

We observe an anomalous oxygen isotope effect on the a-axis component of the far-infrared electronic response of detwinned YBa2Cu3 $^{16, 18}$ O $_{6.9}$ . For $^{18}$ O a pronounced low…
