Magnetic hysteresis properties of interacting and noninteracting micron-sized magnetite produced by electron beam lithography

Muxworthy, A.R.; King, J.G.; Odling, N. (AGU and the Geochemical Society. http://www.agu.org/journals/gc/index.shtml, 2006)

The magnetic hysteresis properties for well-defined micron-sized magnetite samples produced by electron beam lithography (EBL) are presented. In addition to measuring standard hysteresis parameters, first-order reversal ...

Comprehensive experimental and theoretical investigation of solar radiation conditions in Botswana: A semi-desert region

Nijegorodov, N.; Luhanga, P.V.C.; King, J.G. (Regional Energy Resources Information Center (RERIC) Asian Institute of Technology. http://www.rericjournal.ait.ac.th/index.php/reric/index, 2005-12)

Fault-Plane Solutions of the 18 May 2001 earthquake in South Africa near Botswana border

King, J.G.; Garegae, M.; Ngwisanyi, T.H.; Ranganai, R. (Botswana Geoscientists Association, 2005-12)

Fault-plane solutions of an earthquake can provide information about the type of fault. We report on the calculation of the fault-plane solutions of the earthquake that occurred on the morning of 18 May 2001 and was felt ...

Low-temperature magnetic properties of magnetite

King, J.G.; Williams, W. (American Geophysical Union. http://www.agu.org/journals/jd/, 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 ...

Gravity evidence for a larger Limpopo Belt in southern Africa and geodynamic implications

Ranganai, R.T.; Kampunzu, A.B.; Atekwana, E.A.; Paya, B.K.; King, J.G.; Koosimile, D.I.; Stettler, E.H. (Royal Astronomical Society. http://www.wiley.com/bw/journal.asp?ref=0956-540X&site=1, 2002)

The Limpopo Belt of southern Africa is a Neoarchean orogenic belt located between two older Archean provinces, the Zimbabwe craton to the north and the Kaapvaal craton to the south. Previous studies considered the Limpopo ...

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 ...
