Room Temperature Ferromagnetic Semiconductor Rutile Ti1-xCoxO2-δEpitaxial Thin Films Grown by Sputtering Method
Takashi Yamasaki, Tomoteru Fukumura, Masaki Nakano +2
Room temperature ferromagnetic semiconductor rutile Ti1-xCoxO2-δ(101) epitaxial thin films were grown on r-sapphire substrates by a dc sputtering method. Ferromagnetic magnetizatio…
Observation of Fermi-surface-dependent nodeless superconducting gaps in Ba0.6K0.4Fe2As2
H. Ding, P. Richard, K. Nakayama +13
The recent discovery of superconductivity in iron-arsenic compounds below a transition temperature (Tc) as high as 55K ended the monopoly of copper oxides (cuprates) in the family…
Molecular spin resonance in the geometrically frustrated MgCr2O4 magnet by inelastic neutron scattering
K. Tomiyasu, H. Suzuki, M. Toki +4
We measured two magnetic modes with finite and discrete energies in an antiferromagnetic ordered phase of a geometrically frustrated magnet MgCr2O4 by single-crystal inelastic neut…
Crystallographic Phase Transition and High-Tc Superconductivity in LaFeAsO:F
Takatoshi Nomura, Sung Wng Kim, Yoichi Kamihara +6
Undoped LaFeAsO, parent compound of the newly found high-Tc superconductor, exhibits a sharp decrease in the temperature-dependent resistivity at ~160 K. The anomaly can be suppres…
