Magnetic susceptibility behaviour is studied in weak dc and ac magnetic fields in the spin glass–paramagnetism transition region of the system (CuCr2Se4)x (Cu0.5Me0.5Cr2Se4)1−x (Me = In, Ga). The critical exponents γ, δ, and β in the spin glasses with x = 0,0.01 and 0.03 (Me = In) determined from the nonlinear static susceptibility χnl in the region of the freezing temperature T′f are in close agreement with values predicted by the mean field theory, Tf being determined by the maximum value of… CONTINUE READING
