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…

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…
