We present experimental results of complex susceptibility, static magnetization, magnetic relaxation, specific heat, and electrical resistivity measurements on an intermetallic compound Nd[sub 2]AgIn[sub 3]. The results indicated that Nd[sub 2]AgIn[sub 3] undergoes a spin-glass transition at a freezing temperature T[sub f] = 12.6 K accompanied with the formation of short-range antiferromagnetic order. The mechanism of formation of spin-glass state in Nd[sub 2]AgIn[sub 3] is different from that in diluted metallic spin-glass or uranium intermetallic compound. The existences of frustrated moments due to the triangles of nearest neighbors in Nd atomic layers and randomly distributed Ruderman-Kittle-Kasuya-Yosida interactions may be responsible for the spin glass state formed in Nd[sub 2]AgIn[sub 3]. © 2001 American Institute of Physics.
