Description

We present the results of ac and dc susceptibility, magnetic relaxation, specific heat and electrical resistivity measurements on a well-annealed tetragonal ThCr2Si2-type compound CeAu2Si2. These data provide clear evidence for the formation of spin glass state in this system at about Tf ∼ 2.2 K much lower than its Neel temperature TN = 10 K. The mechanism of the observed re-entrant spin-glass behaviour in CeAu2Si2 is discussed by comparing the present results with those reported for the analogue compounds URh2Ge2 and PrAu2Si2
