1 SCANNING! MAGNETIC TUNNEL JUNCTION (MTJ)! MICROSCOPY!! High-resolution magnetic imaging of geologic samples" Ioan Lascu and Richard J. Harrison"
2 OVERVIEW" 1. Scanning magnetic microscopy" 2. MTJ microscopy" 3. Specimens suitable for MTJ scanning " " " " " "" " " Funding: European Research Council" Acknowledgments: Gang Xiao, Matthew Carter, Jay Shah, Adrian Muxworthy, Oliver Shorttle, Jim Miller, Roberts Blukis, Josh Feinberg"
3 1. SCANNING MAGNETIC MICROSCOPY" Technique that allows mapping of field associated with fine-scale magnetic structures" Attractive due to spatial resolution and high sensitivity" Can isolate micro-regions of interest in bulk samples" Complements traditional rock magnetic techniques" Schrag et al. (2006)"
4 SCANNING MAGNETIC MICROSCOPY" Superconducting Quantum Interference Device SQUID (Weiss et al., 2007)" Giant Magnetoresistance GMR (Hankard et al., 2009)" Hall Probe (Kletetschka et al., 2013)" Nitrogen Vacancy Diamond (LeSage et al., 2013)" MTJ (Lima et al., 2014)" GMR high resolution" SQUID high sensitivity"
5 2. MTJ MICROSCOPY" MTJ Sensor thin film device:" - Insulating layer (e.g. MgO) " ~1nm thick a few atomic monolayers " allows quantum tunnelling of electrons" - Magnetic electrodes (e.g. CoFeB)" one is pinned via exchange bias " one is free to respond to magnetic fields" maximum current if magnetic layers are parallel" maximum resistance if antiparallel: >200% change high sensitivity "
6 MTJ MICROSCOPY" MTJ technology: " - read/write heads for disk drives, magnetic memory in semiconductor industry, miniaturized low-field sensors" - no need for cryogens" - small sensor active area" - small biasing current to operate sensor: minimize induced magnetizations in sample (<1 µt)" - all these translate to: small sensor-sample distance, higher resolution, better signal/noise ratios" " Spatial Resolution (µm)" 1000" " 100" " 10" " 1" Schrag et al. (2006)" 0.1 " 1 " 10 " 100 " 1000" Sensor-Sample Distance (µm)"

9 MTJ CAMBRIDGE" Stage on aluminium extension to minimize interference from motor" Optical camera" Two offset sensors per cartridge, one for sample stray fields, one for ambient field" Sample handling is straightforward" Polished surfaces, no need for horizontality" Static mode: calibrated" Vibrating mode: no scanning artifacts" "
10 3. SPECIMENS: SPHERICAL RARE-EARTH MAGNETS" NdFeB spherical powder" - median grain size ~40 µm" - high anisotropy" - calibration and modeling" "
