It is difficult to find a typical compound to understand the spin-glass (SG). Only a few model compounds for the SG have been investigated; Fe0.50Mn0.50TiO3 as a short-range interacting three-dimensional (3D) Ising SG, Dy0.103Y0.897Ru2Si2 as a long-range 3D Ising SG, and AgMn as a long-range 3D Heisenberg SG. A spinel-type compound CuCrTiS4 will be provided in this study as a realistic candidate for a short-range interacting 3D Heisenberg SG. This CuCrTiS4 can cause a SG phase below T g = 7.91 K, which is obtained by a random non-magnetic 50% substitution of Ti for Cr on B-sites in the ferromagnetic mother spinel CuCr2S4. The localized magnetic moment of CuCrTiS4 comes from Cr3+ with S = 3/2, where a valence state of Cu+Cr3+Ti4+S4 2− is built up. Experimental data will be focused only on the static properties of dc magnetization M(T) under various magnetic fields, without any dynamical magnetic feature. The spin-glass phase transition T g is well defined at low field, nevertheless hardly in higher fields than approximately 40 Oe. An appearance of the field dependence of M(T) of CuCrTiS4 is similar to that of Fe0.50Mn0.50TiO3 with the short-range Ising SG, and also these of AgMn and CuMn with the long-range interacting Heisenberg SGs. This general nature in M(T) seems to originate from the common mechanism under magnetic fields for all the spin-glasses.
