Abstract
We report here on low field dc and ac magnetic susceptibility measurements on the compounds SrCr8Fe4-xGaxO19 with x = 0 to x = 4. We have determined their magnetic phase diagram and proved that increasing the Ga content in the structure we cross from ferrimagnetic-like ordering and spin glass reentrance to pure spin glass behaviour and finally to the disapearance of any magnetic ordering in SrCr8GaxO19 as a consequence of the reduced lattice dimensionality.
