## Description

- description: RAlB4 (R = rare earth element) has attracted increasing attention due
    to recent reports on its properties in magnetic, thermoelectric and superconducting
    materials. The authors developed and we investigated the formation of the solid
    solution Yb(Al0.995T0.005)B4 (T = Cr, Mn or Fe) compounds in which the Al position
    of YbAlB4 is substituted with T atoms using the Al flux method. In this study,
    crystals of the boride Yb(Al0.995T0.005)B4 (T =Mo or W) were grown by using Al
    flux mixed with T metal at 1773 K for 5h. Yb(Al0.995W0.005)B4 was obtained as
    the single phase, however, in the case of Yb(Al0.995Mo0.005)B4, a small amount
    of AlMoB crystals was contained. The crystals were measured using a micro-Vickers
    hardness tester, and the oxidation resistance was examined in air using DTA-TG
    apparatus. Comparing the lattice constants and chemical composition of YbAlB4
    and Yb(Al0.995T0.005)B4, it were understood that the lattice constant of Yb(Al,T)B4
    were larger than that of YbAlB4 crystals. Yb(Al,T)B4 were grown as a solid solution
    contained about 40 % of each T metal. The hardness values were 11.0(±0.7) GPa
    for Yb(Al0.995Mo0.005)B4 and 15.7(±1.9) GPa for Yb(Al0.995W0.005)B4. The oxidation
    of Yb(Al,T)B4 starts in the range of 971–987 K. The oxidation onset temperature
    during the heating of Yb(Al,T)B4 is about 100 K higher than YbAlB4.
