Query: Properties of Binary Transition-Metal Arsenides (TAs)   We present thermodynamic and transport properties of transition-metal (T)
arsenides, TAs with T = Sc to Ni (3d), Zr, Nb, Ru (4d), Hf and Ta (5d).
Characterization of these binaries is made with powder X-ray diffraction,
temperature and field-dependent magnetization and resistivity,
temperature-dependent heat capacity, Seebeck coefficient, and thermal
conductivity. All binaries show metallic behavior except TaAs and RuAs. TaAs,
NbAs, ScAs and ZrAs are diamagnetic, while CoAs, VAs, TiAs, NiAs and RuAs show
approximately Pauli paramagnetic behavior. FeAs and CrAs undergo
antiferromagnetic order below TN = 71 K and TN \approx 260 K, respectively.
MnAs is a ferromagnet below TC = 317 K and undergoes
hexagonal-orthorhombic-hexagonal transitions at TS = 317 K and 384 K,
respectively. For TAs, Seebeck coefficients vary between + 40 uV/K and - 40
uV/K in the 2 K to 300 K range, whereas thermal conductivity values stay below
18 W/(m K). The Sommerfeld-coefficient {\gamma} are less than 10 mJ/(K2mol). At
room temperature with application of 8 Tesla magnetic field, large positive
magnetoresistance is found for TaAs (~25%), MnAs (~90%) and for NbAs (~75%).
