The material - 1,3,5-trithia-2,4,6-triazapentalenyl (TTTA) - is non-magnetic at very low temperatures. The paramagnetic effect is strong at room temperature, but as the compound is cooled, it becomes diamagnetic below 230 K. However, it is heated again, it does not become paramagnetic until the temperature reaches is 305K. This is an unusually wide hysteresis loop for a magnetic material.

Fujita and Awaga suggest that the reason for this unusual behaviour is a change in the crystalline structure of the compound. As the structure changes, so do the molecular orbits of unpaired electrons in the crystal. This change increases the electrostatic repulsion pressure on other unpaired electrons in the compound, leading to paramagnetism.
