A single domain grain model for the low-field constricted hysteresis loops of some basaltic rocks

  • C. Radhakrishnamurty
  • N. P. Sastry


Basaltic rocks contain magnetic grains oriented randomly in a nonmagnetic matrix. Experimental studies of low-field hysteresis of such rocks have shown partially and totally constricted hysteresis loops for some specimens. A possible origin of these constricted loops on the basis of interacting single domain behaviour is suggested.
