Magnetic anisotropy of the spin ice compound Dy2Ti2O7
H. Fukazawa, R. G. Melko, R. Higashinaka +2
We report magnetization and ac susceptibility of single crystals of the spin ice compound Dy2Ti2O7. Saturated moments at 1.8 K along the charasteristic axes [100] and [110] agree w…
Incommensurate magnetic ordering in Sr_2Ru_(1-x)Ti_xO_4
M. Braden, O. Friedt, Y. Sidis +3
In the spin excitation spectrum is dominated by incommensurate fluctuations at q=(0.3 0.3 q), which arise from Fermi-surface nesting. We show that upon Ti subst…
Detailed study of the ac susceptibility of Sr2RuO4 in oriented magnetic fields
Hiroshi Yaguchi, Takashi Akima, Zhiqiang Mao +2
We have investigated the ac susceptibility of the spin triplet superconductor SrRuO as a function of magnetic field in various directions at temperatures down to 60 mK. We…
Anisotropy of magnetothermal conductivity in Sr2RuO4
M. A. Tanatar, M. Suzuki, S. Nagai +3
The dependence of in-plane and interplane thermal conductivities of Sr2RuO4 on temperature, as well as magnetic field strength and orientation, is reported. We found no notable ani…
Quasi-particle Density in Sr2RuO4 Probed by means of the Phonon Thermal Conductivity
M. Suzuki, M. A. Tanatar, Z. Q. Mao +2
The thermal conductivity of Sr2RuO4 along the least conducting direction perpendicular to the RuO2 plane has been studied down to 0.3 K. In this configuration the phonons remain th…
Observation of Andreev Surface Bound States in the 3-K phase Region of Sr_2RuO_4
Z. Q. Mao, K. D. Nelson, R. Jin +2
The tunneling spectrum of the superconducting phase with T_c ~ 3.0 K has been measured in the Ru-embedded region of Sr_2RuO_4 using cleaved junctions. A sharp zero-bias conductance…
