✦ Synopsis

Magnetic measurements on the organic radical crystal of 4-(2-naphthylmethyleneamino)-2,2,6,6-tetramethylpiperidin-loxyl exhibited a N6el transition at about 0.12 K (T N) and a metamagnetic transition below T s (the coercive field was around 180 Oe at 40 mK). X-ray crystallographic analysis revealed that the molecules were arranged to give an almost columnar structure with the nearest intermolecular O...O distance of 5.70 .~. The magnetic property was analyzed on the basis of the crystal structure.
