  We present an investigation on the intermetallic compound formed by HoCuBi
which has a monoclinic crystalline P2 structure with lattice parameters; a =
9:8012(26)A, b = 6:0647(6)A, c = 6:1663(13)A. In this report we performed an
extensive analysis of the magnetic characteristics, specific heat at low
temperature mainly close to the region of the observed antiferromagnetic
transition with Neel temperature about 7 K, and to the field induced
spin-crossover; the metamagnetic transition typically observed in
antiferromagnetic systems by measurements of M-H, (Magnetization - Magnetic
Field) at low temperatures.
