changes in magnetic fields in porous media are important because they can influence measurements of the NMR relaxation parameters. Quantification of internal fields can be difficult by NMR alone. To unambiguously and directly quantify the spatial distribution of internal magnetic fields we employ scanning SQUID microscopy. We measured selected grains of a natural sand (obtained from the Ogallala aquifer) with grain sizes of about 200 \u03bcm, and detected relatively high internal magnetic fields (~ 1 mT) and gradients (&gt; 5 T\/m) in a very small background field (~ 2 \u03bcT).<\/p>\n\n            <!-- Main Image -->\n            \n            <!-- Main Link -->\n                        <p class=\"has-vivid-cyan-blue-color has-text-color has-link-color link\">\n                <a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1090780714000305\" style=\"color: #3366ff;\">\n                    Journal of Magnetic Resonance (2014)<\/a>\n            <\/p>\n            \n            <!-- Additional Info -->\n                                                \n                    \t\t\t\t\t\t                        <figure class=\"wp-block-image aligncenter size-full\">\n                            <img decoding=\"async\" src=\"http:\/\/beenalab.biu.ac.il\/wp-content\/uploads\/2014\/06\/Nano-magnetism-1.png\" alt=\"\" class=\"wp-image\"\n                                 \/>\n                        <\/figure>\n\n                                                        \n                    \t\t\t\t\t\t                        <p class=\"has-black-color has-text-color has-link-color\" style=\"font-size:18px\">\n                            With: Jan Walbrecker, Kathryn Moler, Rosemary Knight @ Stanford<\/p>\n\n                                                \n            <!-- Separator -->\n            <hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n        <\/div>\n                <div class=\"article-ctr\">\n            <!-- Title -->\n            <h1 class=\"wp-block-heading auto-style16\"><span style=\"color: #993300;\">\n                Tuning the magnetism in LAO\/STO<\/span><\/h1>\n\n            <!-- Main Content -->\n            <p class=\"has-black-color has-text-color has-link-color\" style=\"font-size:18px\">\n                We are trying to learn more about the microscopic nature of this magnetism by tuning it in different ways.
