Electron Spin resonance of Gd3+in three dimensional topological insulator Bi2Se3

Abstract: Abstract. Bi2Se3 has been claimed to be a three dimensional topological insulator (TI) with topologically protected metallic surface states with exotic properties. We have performed electron spin resonance (ESR) measurements on Gd 3+ doped (x ≈ 0.01) Bi2Se3 single crystal grown from stoichiometric melt. For the studied crystals, our preliminary results revealed a partly resolved Gd 3+ fine structure spectrum with Dysonian (metallic character) lines. At room temperature, the central line has a g ≈ 1.98, a linew… Show more

“…Positron annihilation spectroscopy can provide unique information in the characterization of vacancies and vacancies attached defects ( e . g ., dislocations, misfit defects, and interfaces). , In the case of Bi 2 Te 3 -based alloys doped with transition metals or rare-earth elements, electron spin resonance can explore localized spins and reveal the intensity of electron–phonon coupling, which is important for evaluating TE properties. , The local structure information can be observed via extended X-ray-absorption fine-structure spectra, such as the interatomic distance, the locations of impurity sites, the locational fluctuations around impurity atoms, and the lattice distortions. In turn, the crystallographic structure in detail can provide basic information for first-principles calculations to quantify research on TE properties.…”

“…Moreover, the electron spin resonance of single Gd ions embedded in Bi 2 Se 3 was examined in Ref. 33. The temperature dependence of the g-factor was investigated and the coexistence of a metallic and an insulating phase (dual character) was reported.…”
