  • Determination of magnetite grain-size using the Hopkinson effect - examples from Botswana rocks 

    King, J.G.; Ranganai, R.T. (Botswana Geoscientists Association, 2001)
    The Hopkinson effect is the increase of magnetic susceptibility with temperature from near room temperature to near the Curie point. Although this effect has been known for more than a century, it has not been effectively ...
  • Low-temperature magnetic properties of magnetite 

    King, J.G.; Williams, W. (American Geophysical Union., 200)
    Although several studies have recommended removal of secondary components of magnetic remanence by zero-field cycling from room temperature to a temperature much lower than the low temperature transition for magnetite ...
