Abstract

Magnetization measurement in pulsed high magnetic fields up to 28 T in the range of temperature from 55 to 85 K have been performed for (Nd _0.33Eu_0.38Gd_0.28)Ba₂Cu ₃O_y (NEG123) having very high irreversibility fields B_irr We have evaluated temperature dependence of B_irr by taking account of heat generation. Critical current density in pulsed high magnetic fields was somewhat overestimated in comparison with that in fields, but values of B_irr nearly coincide. B_irr did not strongly depend on the content of Gd₂BaCuO₅ (Gd211) secondary phase between 2 and 10 mol%. The temperature dependence of B_irr can be expressed as B_irr (T) = 80.2-0.878 T (K).
