摘要：

We demonstrate current oscillation phenomena using the negative differential resistance in a one-dimensional halogen-bridged nickel compound, [Ni(chxn)(2)Br]Br-2 (chxn=cyclohexanediamine). By attaching external resistors and a capacitor to a [Ni(chxn)(2)Br]Br-2 sample, we obtain stable current oscillation at 90 K. The oscillation and its period are explained by a simple model.
