MAGNETIC-BEHAVIOR OF THE SPIN-GLASS STATE IN CDCR2XIN2-2XSE4 THIN-FILMS

The interaction parameters describing coupling between the infinite fe rromagnetic network and finite clusters have been studied for CdCr2xIn 2-2xSe4 diluted system. The samples were in a form of thin films obtai ned by rf sputtered technique. We controlled the dilution level by cha nging the indium content. The temperature dependence of low field magn etization was found from SQUID measurements, the results are in good a greement with those predicted for the spin glass magnetic phase with r e-entrant background (or randomly canted compound). The models of rand omly distributed spins proposed by Anderson and Continentino were appl ied. Continentino's model includes two interaction parameters: M (the resonance interaction between the finite and infinite clusters) and D (which is related to the relaxation processes).
