Abstract
The magnetic properties of 4-methacryloyloxy- and 4-acryloyloxy-2,2,6,6-tetramethylpiperidine-l-oxyl (MOTMP and AOTMP, respectively) were studied. The magnetic susceptibility, magnetization, and molar heat capacity of MOTMP show that the crystal has one-dimensional ferromagnetic coupling, and that the coupling between the one-dimensional coupling chains was antiferromagnetic, resulting in a metamagnet below 0.16 K. On the other hand, AOTMP, where hydrogen atom is substituted for a methyl group at α-position, shows an antiferromagnetic coupling between the nitroxyl radicals.
