Résumé

The magnetic properties of the spinel compound Cu1.30Cr1.30Zr0.70Se4 have been studied using, magnetic measurements. These measurements (DC) reveal that Cu1.30Cr1.30Zr0.70Se4, orders ferromagnetically-re-entrant spin-glass. The geometrical spin frustration is introduced through
antiferromagnetic interactions due to the substitution of magnetic Cr for Zr atom, on the B sites forming a network of linked tetrahedral. The magnetization in field-cooled (FC) and zero-fieldcooled (ZFC) are observed with irreversibility in T≤ Tf, the overage Curie temperature, the effective magnetic moment and the temperature range, for which magnetic susceptibility can be regarded as linear are given.
