CADENAS, R et al. Transición de Spin-Flop inducida por un campo magnético pulsado en el compuesto MnGa₂Se₄. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.195-197. ISSN 0035-001X.

Measurements of static magnetic susceptibility as a function of temperature (x vs. T) and magnetization as a function of the magnetic field (M vs. B) have been made on a polycrystalline sample of MnGa₂Se₄. The obtained results show that the MnGa₂Se₄ is an antiferromagnetic material (AFM) with Néel temperature T_N=8.2 K. For T<T_N and B2 Tesla a transition occurs from the antiferromagnetic (AF) phase to the spin-flop(SF) phase where the spins are perpendicular to the field.
