We report the synthesis of small single crystals of several RERh4B4 compounds where RE=Sm, Gd, Tb, Dy, Ho, Er, and Tm using a flux-growth technique. Measurements of the ac electrical resistance R in zero and applied magnetic fields and dc magnetic susceptibility are reported. The upper critical magnetic field Hc2(T) determined from the resistance measurements for RE=Sm, Er, and Tm are also presented. Considerable anisotropy of Hc2(T) is observed for Er and Tm, while very little is found for Sm.
