Abstract

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.
