Notes:
The pseudo-one-dimensional mixed system [(CH3)3NH]Co1−xNixCl3 2H2O was found to exhibit spin-glass behavior below a characteristic temperature evidenced by the onset of time-dependent thermoremanent magnetization. In order to confirm the spin-glass behavior we now have studied the ac susceptibility of this series in zero field using an ac SQUID susceptometer. Along the weak ferromagnetic axis (a axis), the ac susceptibility shows a cusp at the spin-glass transition temperature. Increasing the measurement frequency from 80 to 160 Hz increases the slope of the susceptibility below the transition temperature but no significant shift in the transition temperature itself is seen for this small frequency range. Spin-glass behavior is seen only along the a axis and a typical antiferromagnetic transition is seen along the c axis.
