CrSb film was deposited on KCl (100) substrates by magnetron sputtering. Strong ferromagnetism was observed in the CrSb film, which can be attributed to the CrSb phase with ferromagnetic zinc-blended structure. The investigated ZB-CrSb film about 5 nm in

The extension of magnon electron drag (MED) to the paramagnetic domain has recently shown that it can create a thermopower more significant than the classical diffusion thermopower resulting in a thermoelectric figure-of-merit greater than unity. Due to their distinct nature, ferromagnetic (FM) and antiferromagnetic (AFM) magnons interact differently with the carriers and generate different amounts of drag-thermopower. The question arises of whether the MED is stronger in FM or in AFM semiconductors. Two material systems, namely MnSb and CrSb, which are similar in many aspects except that the former is FM and the latter AFM, were studied in detail, and their MED properties were compared. Three features of AFMs compared to FMs, namely double degeneracy of the magnon modes, higher magnon group velocity, and longer magnon relaxation time, can lead to enhanced first-order MED thermopower. One effect, magnon-electron relaxation, leads to a higher second-order effect in AFMs that reduces the MED thermopower. However, it is generally expected that the first-order effect dominates and leads to a higher drag thermopower in AFMs, as seen in this case study.

Cr1+tSb1-xTex has been investigated for 0.00 x 0.50 for the series CrSb1-xTex and Cr1.05Sb1-xTex by powder X-ray and neutron diffraction, DSC and magnetic susceptibility measurements.Cr1+tSb1-xTex takes the NiAs-type structure.Cr1+tSb1-xTex has a homogeneity range on the Cr-rich side, here only examined for t=0.05, which, however, nearly coincides with the upper limit.For increasing x, the homogeneity range narrows, and the metal enrichment is probably absent for x > ca. 0.20.The Curie-Weiss law is satisfied for all samples in the high-temperature paramagnetic regime.The cooperative magnetic state changes from typically antiferromagnetic for x=0.00 to ferromagnetic-like for x=0.50.A slight reduction in the Neel temperature is observed for the t=0.05 series when x N is reduced from 680 K for x=0.00 to 180 K for x ca. 0.50.For ca. 0.15 x ca. 0.50 more than one cooperative state (antiferro- and canted magnetic arrangements) exist at low temperatures.The magnetic phase diagram for 0.00 x 0.50 is reconsidered.
