The magnetic properties of Mn-doped Bi2Te3 were studied by a combination of complementary magnetic measurement techniques which are sensitive to the bulk, 'thin film' and surface properties.
While SQUID and torque magnetometry, as well as μSR and magnetotransport give access to bulk properties, XMCD is mostly sensitive to the surface and near-surface areas of the materials. 3.1. Magnetization measurements SQUID magnetometry was performed as a function of temperature and magnetic field, in different orientations with respect to the ab-plane, using a 7 T quantum design magnetic properties measurement system, with results shown in figure 5. The hysteresis loops measured on xn = 0.15 crystals show that the samples are soft ferromagnets with small coercive fields of ~ 70 mT at 1.8 K (for H||c), as shown in figure 5(a), with a saturation magnetic moment of 4.4(5) μB per Mn atom reached at ~ 1.5 T.

Topological phases and quasiparticle braiding. Statistical mechanics - How Non-abelian anyons arise in solid-state systems. The realization of non-Abelian statistics in condensed matter systems was first proposed in the following two papers.
G. Moore and N. Read, Nucl. Phys. B 360, 362 (1991) X. Zhenghan Wang and I wrote a review article to explain FQH state (include non-Abelian FQH state) to mathematicians, which include the explanations of some basic but important concepts, such as gapped state, phase of matter, universality, etc. The key point is the following: consider a non-Abelian FQH state that contains quasi-particles (which are topological defects in the FQH state), even when all the positions of the quasi-particles are fixed, the FQH state still has nearly degenerate ground states. When there is the quasi-particle induced topological degeneracy, as we exchange the quasi-particles, a non-Abelian geometric phase will be induced which describes how those topologically degenerate ground states rotated into each other.
