Low-temperature spin state in an organic spin-liquid candidate κ-(BEDT-TTF)2Cu2(CN)3 investigated by magnetization measurements — •Eria Imada1, 2, Yosuke Matsumoto2, Pal Sudip3, Naoki Yoneyama4, Martin Dressel3, Takahiko Sasaki5, Kazushi Kanoda1, 2, 3, and Hidenori Takagi1, 2, 31The University of Tokyo, Tokyo, Japan — 2Max-Planck-Institute, Stuttgart, Germany — 3University of Stuttgart, Stuttgart, Germany — 4Yamanashi University, Kofu, Japan — 5Tohoku University, Sendai, Japan

The ground state of the organic quantum spin liquid candidate, κ-(BEDT-TTF)2Cu2(CN)3, is under debate. We report our detailed DC magnetization M measurements. M(T) on cooling shows a rapid decrease with a clear kink at 6K but an appreciable residual contribution, nearly liner in magnetic field up to 7 T, remains even at 2 K. We discuss possible origin of the low temperature residual contribution.
