抄録

We report the results of susceptibility and magnetization measurements on ferromagnetic-antiferromagnetic alternating chain compounds [Cu(TIM)]CuCl_4 (TIM=2, 3, 9, 10-tetramethyl-1, 3, 8, 10-tetraenecyclo-1, 4, 8, 11-tetraazatetradecane) and (4-BzpipdH)CuCl_3 (4-BzpipdH=4-benzylpiperidinium). Magnetization curves of both compounds are compared to those calculated for an S=1 linear-chain Heisenberg antiferromagnet. From the fitting of susceptibility data to a numerical formula calculated for an S=1/2 ferromagnetic-antiferromagnetic alternating chain [Inog. Chem. {33} (1994) 5171], we have estimated theantiferromagnetic exchange constant J_AF/k_B=2.9 K, the ferromagnetic exchange constant |J_F|/k_B=4.7 K and the g-value of the magnetic moment g=2.06 for the former and J_AF/k_B=8.8 K, |J_F|/k_B=38.8 K and g=2.17 for the latter, which are different from the values reportedpreviously.
