Phase diagrams of two dilute insulating systems with competing interactions: CdCr2xIn2-2xS4 and ZnCr2xAl2-2xS4
M. Alba,J. Hammann,M Nogues +2 more
TL;DR: In this paper, the results for the ferromagnetic system were compared with theoretical predictions derived from a bond-diluted Ising model using the replica method and a second-order variational approximation.
Journal ArticleDOI
Observation of a spin-glass behavior of the susceptibility in a dilute chromium spinel
M. Alba,J. Hammann,M. Nogues +2 more
TL;DR: In this article, low field dc and ac susceptibility measurements have been performed on several samples of the CdCr2xIn2x−2S4 spinel system and a tentative phase diagram is proposed.
