Magnetic susceptibility inversion method with full tensor gradient data using low-temperature SQUIDs

Abstract Full tensor magnetic gradient measurements are available nowadays. These are essential for determining magnetization parameters in deep layers. Using full or partial tensor magnetic gradient measurements to determine the subsurface properties, e.g., magnetic susceptibility, is an inverse pr...
