摘要
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 at T > 20 K.
