Critical behavior of spinel vanadate oxide MnV2O4 has been investigated by the dc-magnetization study. Critical exponents β = 0.349 ± 0.009, γ = 0.909 ± 0.002, and δ = 2.913 ± 0.003 are obtained in the critical asymptotic region around the critical temperature TC. With these critical exponents, expe...
