Simultaneous determination of intergranular interactions and intrinsic switching field distributions in magnetic materials
We develop a generally applicable method for the accurate measurement of intrinsic switching field distributions and the determination of exchange and dipolar interactions in granular magnetic materials. The method is based on the simultaneous analysis of hysteresis loop and recoil curve data. Its v...

| 520 | |a We develop a generally applicable method for the accurate measurement of intrinsic switching field distributions and the determination of exchange and dipolar interactions in granular magnetic materials. The method is based on the simultaneous analysis of hysteresis loop and recoil curve data. Its validity and practical implementation are demonstrated by means of computational modeling using a reference function identification scheme. We find the methodology to be numerically accurate in a wide parameter range, far exceeding the previously utilized mean-field interaction regime used in other methodologies. | ||
