## Description

- description: This study investigates the thermoelectric properties of p-type Bi0.5Sb1.5Te3
    with added 10% Te composites containing a varying ratio of the ferromagnetic semiconductor
    of CrSb (0, 0.125, 0.5, and 1 wt.%) as a secondary phase. Samples were synthesized
    by a combination of ball milling and spark plasma sintering techniques. The incorporation
    of CrSb particles resulted in an increase in thermopower due to an increase in
    the effective mass of the charge carriers, indicating that there is a drag effect
    originating from the magnetic particles. However, this was at the expense of reduced
    electrical conductivity due to reduced carrier mobility. While overall only marginal
    improvements in power factors were observed, the multiphase samples exhibited
    significantly lower thermal conductivity compared to the single-phase material.
    As a result, a peak zT value of ∼1.4 was achieved at 325 K for the sample with
    0.125 wt.% CrSb. The synergistic effects of magnetically induced thermopower enhance-
    ment and thermal conductivity reduction resulted in showing the potential of incorporating
    magnetic secondary phases to optimize the thermoelectric performance in this system
