Mn-substitution effects on MgB2 superconductor
Sheng Xu, Yutaka Moritomo, Kenichi Kato +1
Effects of magnetic impurity on the superconductivity has been investigated in Mg1-xMnB2. With increase of Mn concentration x, the lattice constant c (perpendicular to the boron sh…

Observation of anomalous single-magnon scattering in half-metallic ferromagnets by chemical pressure control
T. Akimoto, Y. Moritomo, A. Nakamura +1
Temperature variation of resistivity and specific heat have been measured for prototypical half-metallic ferromagnets, R_0.6Sr_0.4MnO_3, with controlling the one-electron bandwidth…

Optical spectra measured on cleaved surfaces of double-exchange ferromagnet La1-xSrxMnO3
K. Takenaka, K. Iida, Y. Sawaki +3
Optical reflectivity spectra were measured on cleaved surfaces of La1-xSrxMnO3 single crystals (x=0.175, T_C=283 K) over a temperature range 10-295 K. The optical conductivity $sig…
