Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -
Detection of Spin-Polarized Conduction Electrons in Si by MuSR
One of the challenges of developing Silicon-based spintronics technology is developing non-destructive methods for characterizing spin-polarized conduction electrons. Si is... -
The 400 meV excitation in LSCO and its doping dependence
Neutron scattering techniques at the time-of-flight spectrometers at ISIS have shown that there is a well defined excitation with an energy of about 400 meV in YBCO. A similar... -
Time reversal symmetry breaking in superconducting PrOs4Sb12 and its alloys
In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in... -
Control of the electronic state in new pnictide superconductors using doping
