The dramatic temperature dependence of the magnetic susceptibility and Electron Spin Resonance in sodium superoxides between 77 and 300 K is attributed to various structural phase transitions. One of our important observations is a switchover from a weak ferromagnetically coupled 3-dimensional system to a strong antiferromagnetically coupled 1-dimensional system with decreasing temperature. There is no magnetic ordering. |
