Magnetic detection and characterization of biogenic magnetic minerals: A comparison of ferromagnetic resonance and first-order reversal curve diagrams

Chang, Liao; Roberts, Andrew P.; Winklhofer, Michael; Heslop, David; Dekkers, Mark J.; Krijgsman, Wout; Fitz Gerald, John D.; Smith, Paul


Biogenic magnetic minerals produced by magnetotactic bacteria occur ubiquitously in natural aquatic environments. Their identification and characterization are important for interpretation of paleomagnetic and environmental magnetic records. We compare two magnetic methods for their identification and characterization in a diverse set of sedimentary environments: ferromagnetic resonance (FMR) spectroscopy and first-order reversal curve (FORC) diagrams, constrained by transmission electron...[Show more]
