Abstract Materials with both large magnetocaloric response and high thermoelectric performance are of vital importance for all-solid-state thermoelectromagnetic cooling. These two properties, however, hardly coexist in single phase materials except previously reported hexagonal Cr$_{1-x}$Te half metal where a relatively high magnetic entropy change $(-\Delta S_{\rm M})$ of $\sim 2.4 $ J$\cdot $kg$^{-1}\cdot$K$^{-1}$ @ 5 T and a moderate thermoelectric figure of merit (ZT) of $\sim 1.2\times 10^{-2}$ @ 300 K are simultaneously recorded. Herein we aim to increase the thermoelectric performance of Cr$_{1-x}$Te by compositing with semiconducting Ag$_{2}$Te. It is discovered that the in-situ synthesis of Cr$_{1-x}$Te/Ag$_{2}$Te composites by reacting their constitute elements above melting temperatures is unsuccessful because of strong phase competition. Specifically, at elevated temperatures ($T > 800 $ K), Cr$_{1-x}$Te has a much lower deformation energy than Ag$_{2}$Te and tends to become more Cr-deficient by capturing Te from Ag$_{2}$Te. Therefore, Ag is insufficiently reacted and as a metal it deteriorates ZT. We then rationalize the synthesis of Cr$_{1-x}$Te/Ag$_{2}$Te composites by ex-situ mix of the pre-prepared Cr$_{1-x}$Te and Ag$_{2}$Te binary compounds followed by densification at a low sintering temperature of 573 K under a pressure of 3.5 GPa. We show that by compositing with 7 mol% Ag$_{2}$Te, the Seebeck coefficient of Cr$_{1-x}$Te is largely increased while the lattice thermal conductivity is considerably reduced, leading to 72% improvement of ZT. By comparison, $-\Delta S_{\rm M}$ is only slightly reduced by 10% in the composite. Our work demonstrates the potential of Cr$_{1-x}$Te/Ag$_{2}$Te composites for thermoelectromagnetic cooling.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
