Abstract
The magnetization of oriented single crystals of the Haldane gap material (CH3)4N[Ni(NO2)3], more commonly known as TMNIN, has been measured using a capacitive platform magnetometer operating in magnetic fields up to 8 T at temperatures down to 25 mK. In addition, powdered samples have been studied by standard induction techniques in pulsed fields up to 50 T at 4 K. The results of our preliminary investigations, which probe the anisotropy of the critical magnetic field, are presented.
