Description:
By separating the test sample of Haruna pumice at 300°C, the ferromagnetic mineral grains showing self-reversal of thermo-remanent magnetism (Reverse T.R.M.) (1) were classified into three types A, AB and B. The measurement of Js-T curve and T.R.M. characteristics of each type revealed that the sole component responsible for Reverse T.R.M. is the grains AB, each of which containing both of the constituents of types A and B in itself. It was concluded that the appearance of Reverse T.R.M. is a result of magnetic interaction between magnetic domains of the constituents A and B in the grains of type AB during cooling under a weak magnetic field. © 1952, Society of Geomagnetism and Earth, Planetary and Space Sciences.
