Abstract

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 TN=8.2 K. For T<TN 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.

Keywords : Magnetic transitions; antiferromagnetics; magnetic semiconductors.
