| Abstract | Introducing magnetic elements or nanoparticles into the thermoelectric matrix is of great importance to regulate the thermoelectric perform
ance and evaluate the magnetic-thermoelectric effect. While, the limitation of solid solution ability of magnetic elements in thermoelectric mater
ials impedes the development of magnetic thermoelectric matrix. Herein, we have applied high entropy strategy to alloy a large amount of Cr ele
ments into the Bi2Se3 sub-lattice, and successfully obtained a single-phase magnetic thermoelectric material in the nominal composition of
Bi0.6Sb0.6In0.4Cr0.4Se3 . The Magnetization loop curves of Bi0.6Sb0.6In0.4Cr0.4Se3 sample shows obvious ferromagnetic behavior with a coercivity of
2000 Oe and residual magnetization of 0.22 emu g−1 at 2 K. The temperature dependence of zero-field-cooled magnetic susceptibility and field
cooled magnetic susceptibility reveals a transition from ferromagnetism to paramagnetism at 61 K. These findings indicate that a magnetic Bi2Se3
based thermoelectric material is successfully obtained. The corresponding structure, magnetic and thermoelectric properties are also carefully
discussed. This work offers a new avenue to achieve a magnetic thermoelectric material through high entropy strategy. |
