摘要: Abstract The pinning force scaling is analyzed for various samples of the ternary compound (Nd,Eu,Gd)Ba 2 Cu 3 O x with different types additions (211 particles, Ag O, nanoparticles) and variation Nd:Eu:Gd content. As already observed in earlier experiments, a well-developed behavior normalized flux versus applied field obtained all studied here temperature range 60 ⩽  T  ⩽ 95 K. These curves are detail employing approaches Dew-Hughes Kramer, also several newer, more elaborated models, which enable to judge about coexistence mechanisms operating simultaneously.
