An alternative experimental method to discriminate magnetic phases using IRM acquisiton curves and magnetic demagnetisation by alternating field

Separation of different magnetic phases in natural samples composed by a mix of several magnetic minerals become necessary in rock magnetism in order to identify and describe the main magnetic carriers. However, this task may be difficult to carry out successfully. The goal of the proposed method in this paper is to determine and discriminate experimentally magnetic (soft and hard) phases in synthetic and natural samples. The present method uses two different magnetic techniques, isothermal remanent magnetisation acquisition and magnetic demagnetisation alternately. After the entire process of...
