FORC在岩石磁学中的应用:从非线性测量到磁畴状态的识别

摘要

First-order reversal curve(FORC)diagrams[Pike et al.,1999;Roberts et al.,2000]have become a standard method for identifying magnetic minerals,their grain-size(domain state)and magnetostatic interactions among magnetic particles.FORC diagrams containmuch useful information that magnetic hysteresis loops and isothermal remanentmagnetization acquisition curves cannot provide[e.g.,Roberts et al.,2000,2014],particularly concerning magnetostatic interaction distributions and domain states ofmagnetic particles.
