Spin-Spin Correlation Enhanced by Impurities in a Frustrated Two-leg Spin Ladder
Takanori Sugimoto, Michiyasu Mori, Takami Tohyama +1
We theoretically study a spin-spin correlation enhanced by non-magnetic impurities in a frustrated two-leg spin ladder. The frustration is introduced by the next-nearest-neighbor a…
Possible method to observe breathing mode of magnetic domain wall in Josephson junction
M. Mori, W. Koshibae, S. Hikino +1
A magnetic domain wall (DW) behaves as a massive particle with elasticity. Sliding and oscillation of the DW have been observed experimentally, whereas vibration of a width in the…
Temperature Dependence of Thermopower in Strongly Correlated Multiorbital Systems
M. Sekino, S. Okamoto, W. Koshibae +2
Temperature dependence of thermopower in the multiorbital Hubbard model is studied by using the dynamical mean-field theory with the non-crossing approximation impurity solver. It…
Zero-Field Fiske Resonance Coupled with Spin-waves in Ferromagnetic Josephson Junctions
S. Hikino, M. Mori, S. Maekawa
AC Josephson current density in a Josephson junction with DC bias is spatially modulated by an external magnetic field, and induces an electromagnetic (EM) field inside the junctio…
Frustration effect on magnetic excitations in a two-leg spin-ladder system
Takanori Sugimoto, Michiyasu Mori, Takami Tohyama +1
We theoretically study the magnetic excitations in a frustrated two-leg spin-ladder system, in which antiferromagnetic exchange interactions act on the nearest-neighbor and next-ne…
