The magnetic properties of nickel-iodine boracite were investigated in the paramagnetic and weakly ferromagnetic states. A decrease and a reversal of the sign of the magnetization with increasing field were observed below 68 °K in a magnetic field exceeding 3 kOe along the axis perpendicular to the spontaneous magnetization direction, and when the sample vibrated along the magnetizing field.
