Description

We studied the solid solution Ba(FexGa1-x)2O4 using X-ray diffraction, neutron diffraction, and Mössbauer effect. As with the study of the solid solution Ba(Fe xAl1-x)2O4, we highlighted a critical concentration xc = 0.41. If x < xc, there is no long-range magnetic order but a superparamagnetic behavior of fine grains. If xc < x < 0.8, there is an antiferromagnetic arrangement of spins along the c-axis of the hexagonal lattice.

Abstract (French)

Nous avons étudié aux rayons X, par diffraction neutronique et effet Môssbauer, la solution solide Ba(FexGa1-x) 2O4. Comme pour l'étude de la solution solide Ba(Fe xAl1-x)2O4, nous avons mis en évidence une concentration critique xc = 0,41. Si x < x c, il n'y a pas d'ordre magnétique à longue distance mais un comportement de grains fins superparamagnétiques. Si xc < x < 0,8, il existe un arrangement antiferromagnétique des spins selon l'axe c de la maille hexagonale.
