Yang, Lei and Chen, Zhi-Gang and Nie, Tianxiao and Han, Guang and Zhang, Zhi and Hong, Min and Wang, Kang L. and Zou, Jin (2016) Co-doped Sb2Te3 paramagnetic nanoplates. Journal of Materials Chemistry C, 4 (3). pp. 521-525. ISSN 2050-7526

Abstract

Co-doped Sb2Te3 nanoplates are fabricated using a facile and green solvothermal method. The as-synthesized nanoplates show uniform hexagonal morphology with a distribution of 1-2 μm in diameters and ∼50 nm in thickness. The detailed structural and compositional characterization indicates that Co uniformly distributes in Sb2Te3 and leads to a lattice shrink of 1.22% along the a axis and 0.9% along the c axis. A Superconducting Quantum Interference Device magnetometer is used to determine the temperature dependent magnetization in zero-field cooled and field cooled processes. The paramagnetic state in our Co-doped Sb2Te3 nanoplates is found from 5 K to 300 K.
