Mitglied in der Helmholtz-Gemeinschaft Surface Effects. Spin canting In a particle of radius 4 nm, about 50% of atoms lie on the surface. The concept of a well-defined super-moment breaks down. In real particles, the surface region thickness is very sensitive to particle shape distortion, surface roughness, surface impurities, defects (like vacancies), compositional inhomogeneity, surface chemical bonds with environment, etc. • Krycka, K.L., Booth, R.A., Hogg, C.R., et al., PRL 104 (2010) 207203
