Dynamic magnetic properties of mn doped YBa2Cu3O7_δ superconducting ceramics / S. A. Halim … [et al.]
AC complex susceptibility, X = X' + i X", measurements were done on the YBa2Cu3O7_δ superconducting samples doped with Mn at Y, Ba and Cu sites Y123 with nominal starting composition (x = 0.02 and 0.1). The data of X' shows that the coupling of the grains in samples that doped at Cu s...

| description | AC complex susceptibility, X = X' + i X", measurements were done on the YBa2Cu3O7_δ superconducting samples doped with Mn at Y, Ba and Cu sites Y123 with nominal starting composition (x = 0.02 and 0.1). The data of X' shows that the coupling of the grains in samples that doped at Cu site are weaker than that samples doped at Y and Ba sites as shown by using the Ambegaokar-Baratoff equation 10 = 1.57 x 108Tc2-/( Tc-Tej), the calculated values of Josephson current, 10 where 1o(in y > l0(in Ba) > 10(in Cu) due to the weakening of the grain's coupling. This observation is supported by the intrinsic coupling loss, Tp obtained from X" that shows a bigger shift of the intergranular coupling peak, Tp, towards lower temperature in Mn doping at Cu site as compared to the doping in Ba and Y sites. Hence the effect of doping is obvious at higher concentration for all samples. Analysis based on the sensitivity of the data of dx'/dT versus temperature furnished further information on the two step transition related to the coupling of the grains in all systems. |
