Abstract :
Magnetic measurements on the organic radical crystal of 4-(2-naphtylmethyleneamino)-2,2,6,6-tetramethylpiperidin-1-oxyl exhibited a Néel transition at about 0.12 K (TN) and a metamagnetic transition below TN (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 Å. The magnetic property was analyzed on the basis of the crystal structure.
