摘要研究了两种硝基氮氧化物（4,4,5,5-四甲基-4,5-二氢- 1h -咪唑-1-氧基- 3-氧化物）自由基在0.5 K和9 t温度下表现为近各向同性S= 1 / 2交替线性链的磁性，五氟苯基硝基氮氧化物在低温下表现为交替的反铁磁链，而材料在室温下表现为均匀的链状结构。2-甲基硝基氮氧化物含有一个具有铁磁和反铁磁相互作用的交替链，在1.3 K时表现出三维相变。
Abstract Magnetic properties of two nitronyl nitroxide (4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1-oxyl 3-oxide) radicals which show nearly isotropic S=½ alternating linear chains are investigated down to 0.5 K and up to 9 T. Pentafluorophenyl nitronyl nitroxide at low temperatures shows an antiferromagnetic chain with alternation, while the material at room temperature shows a uniform chain structure. 2-Methyl nitronyl nitroxide, which contains an alternating chain with ferromagnetic and antiferromagnetic interactions, exhibits a three-dimensional phase transition at 1.3 K.
