The effect of hydrostatic pressure up to 15 kbar on the superconducting transition temperature T, is reported for five compounds in the quatemary system RENi,B& (RE=Y, Lu, Tm, Er, Ho). The compounds with RE=Y, Lu, Tm, Er display a modest linear variation of T, with pressure. The value of dT,/dp is r
The title compounds were synthesized by high pressure/high temperature reactions. TEM revealed the existence of three types of superstructures of the T-structure, which were also observed by powder and single crystal x-ray diffraction. The result of an average structure refinement with the T' unit c
