Electron paramagnetic resonance studies of human liver tissues
Lyophilized samples of human liver have been investigated by means of electron paramagnetic resonance spectroscopy and conventional magnetic methods over the temperature range of 4–300 K. The experimental results exhibit two main magnetic contributions. One of them can be attributed to Fe2+ ions of hemoglobin and the second one, originating from the Fe3+ ions of ferritin grains, shows a transition into the superparamagnetic state atT>20 K.
