| Popis: | The shape sensitivity of a dispersed hematite Mossbauer spectrum to the way of particle packing is detected experimentally. This effect is shown to result from reversible particle transition from superparamagnetic to superferromagnetic state due to correlation bounds arising between magnetization vectors of neighboring particles. |
