Magnetic properties of the Gd5Co50Al45 alloy
Source abstract
Abstract
Abstract The random-exchange spin-glass-like alloy Gd5Co50Al45 is prepared and characterized using DC magnetization, DC relaxation, thermoremanent magnetization and AC magnetic measurements. The freezing of the magnetic moments below T f ∼36 K is studied employing dynamic scaling analysis. The results of the analysis show that the alloy undergoes a paramagnetic – cluster-glass transition upon cooling. The estimated values of the critical exponents of the disordered phase are: zν=9.4, the shortest relaxation time of the system τ 0 =10 −12 s , and the order parameter exponent β=0.65. The temperature of the phase transition is T g =35.5 K .
