FORCopedia: Catalog of First-Order Reversal Curve (FORC) Diagrams

Sample: Bjurbole-L1
Raw data file: Bjurbole-L1i3-grad0.1.frc
Description: Chondrule from Bjurbole Meteorite. The effect of varying the gradient on the MicroMag AGM was tested with the gradient set to 0.1 for this sample and to 0.01 for one of the images below.
