“…The nonlinear contribution to the total magnetic susceptibility shows a divergent tendency when approaching the critical temperature from above, as shown in figure 5. Similar behaviour has been reported for other spin-glass systems [21,[28][29][30][31][32][33]. This divergent behaviour has been interpreted as evidence for the true spin-glass transition.…”

This work reports on magnetic measurements of the quasi-two-dimensional (quasi-2D) system Zn 1−x Mn x In 2 Se 4 , with 0.01 x 1.00. For x > 0.67, the quasi-2D system seems to develop a spin-glass behaviour. Evidence of a true phase transition phenomenon is provided by the steep increase of the nonlinear susceptibility χ nl when approaching T C from above. The static scaling of χ nl data yields critical exponents δ = 4.0 ± 0.2, φ = 4.37 ± 0.17 and T C = 3.4 ± 0.1 K for the sample with x = 1.00 and similar values for the sample with x = 0.87. These critical exponents are in good agreement with values reported for other spin-glass systems with short-range interactions.
