The Singularity Paramagnetic Peak of Bi(0.3)Sb(1.7)Te(3) with p-type Surface State
The magnetization measurement was performed in the Bi(0.3)Sb(1.7)Te(3) single crystal. The magnetic susceptibility revealed a paramagnetic peak independent of the experimental temperature variation. It is speculated to be originated from the free-aligned spin texture at the Dirac point. The ARPES re...

Sumario: | The magnetization measurement was performed in the Bi(0.3)Sb(1.7)Te(3) single crystal. The magnetic susceptibility revealed a paramagnetic peak independent of the experimental temperature variation. It is speculated to be originated from the free-aligned spin texture at the Dirac point. The ARPES reveals that the Fermi level lies below the Dirac point. The Fermi wavevector extracted from the de Haas–van Alphen oscillation is consistent with the energy dispersion in the ARPES. Our experimental results support that the observed paramagnetic peak in the susceptibility curve does not originate from the free-aligned spin texture at the Dirac point. |
