概要

• 論文の詳細を見る

• A series of magnetic compounds with the formula (CuX)LaB_2O_7 and (CuCl)A_2B_3O_<10> (X=Cl, Br; A=Ca, Sr; B=Nb, Ta) have been prepared through a low-temperature topochemical route starting from nonmagnetic double- (n=2) and triple- (n=3) layered perovskites, respectively. The magnetic susceptibility of these compounds typically exhibits a broad maximum at low temperatures, characteristic of low-dimensional antiferromagnetic compounds. However, depending on the choice of the parameters, X, A, B and n, physical quantities such as the Weiss temperature and the temperature at a maximum susceptibility vary to a great extent, which enables us to study the phase diagram of the S=1/2 frustrated square-lattice antiferromagnets (the so-called J_1-J_2 model). In particular, (CuCl)LaNb_2O_7, possibly having a ferromagnetic J_1 and an antiferromagnetic J_2, shows a spin-liquid behavior with the spin gap of 27K.
