Phonon softening and "forbidden" mode observed by Raman scattering in Na0.5CoO2
Q. M. Zhang, M. an, S. K. Yuan +6
Polarized Raman scattering measurements have been performed on Na0.5CoO2 single crystal from 8 to 305 K. Both the A1g and E1g phonon modes show a softening below Tc1 ~ 83 K. Additi…

Spin-valve effect and magnetoresistivity in single crystalline Ca3Ru2O7
Wei Bao, Z. Q. Mao, Z. Qu +1
The laminar perovskite Ca3Ru2O7 naturally forms ferromagnetic double-layers of alternating moment directions, as in the spin-valve superlattices. The mechanism of huge magnetoresis…
