Helical order and multiferroicity in the $S = 1/2$ quasi-kagome system KCu $_{3}$ As $_{2}$ O $_{7}$ (OD) $_{3}$

Gøran J. Nilsen, Yoshihiko Okamoto, Hajime Ishikawa +7

Several Cu $^{2 +}$ hydroxide minerals have recently been identified as candidate realizations of the $S = 1/2$ kagome Heisenberg model. In this context, we have studied the distorted…

Kagome-Triangular Lattice Antiferromagnet NaBa2Mn3F11

Hajime Ishikawa, Tsuyoshi Okubo, Yoshihiko Okamoto +1

A new type of magnetically frustrated lattice is found in the layered fluoride NaBa2Mn3F11. A kagome-type array of regular triangles composed of Mn2+ ions (spin 5/2) deforms so as…
