abstract = {By means of polarized small-angle neutron scattering, we
have resolved the long-standing challenge of determining the
magnetization distribution in magnetic nanoparticles in
absolute units. The reduced magnetization, localized in
non-interacting nanoparticles, indicates strongly particle
shape-dependent surface spin canting with a 0.3(1) and
0.5(1) nm thick surface shell of reduced magnetization found
for similar to 9 nm nanospheres and similar to 8.5 nm
nanocubes, respectively. Further, the reduced macroscopic
magnetization in nanoparticles results not only from surface
spin canting, but also from drastically reduced
magnetization inside the uniformly magnetized core as
compared to the bulk material. Our microscopic results
explain the low macroscopic magnetization commonly found in
nanoparticles.},
