Abstract
Analisis sistematis telah dilakukan pada dua sampel Kristal tunggal Bi2Sr2CaCu2Os s (Bi-2212) dengan kandungan oksigen berbeda yang mempunyai Tc = 93 K dan 70 K dan berada dalam pengaruh medan magnetik antara 0 < H < 40 kOe yang diarahkan sejajar sumbu-c kristal. Model panjang koherensi termodifikasi yang diperkenalkan oleh Rydh, dkk telah memberikan penjelasan yang konsisten perilaku vorteks gelas dengan memberikan nilai eksponen kritis s vorteks gelas (s) yakni 4, 7 dan 2,0 berturut-turut untuk sampel yang bersesuaian. Selain itu penskalaan kurva pada model ini memberikan nilai parameter pinning (fl) berturut-turut 0.45 dan 0,54 untuk kedua kristal.

A systematic analysis has been performed on the resistivity of the Bi2Sr2CaCu2Os s (Bi-2212) single crystals with various oxygen content having Tc = 93 K and 70 K and measured in magnetic field of 0 < H < 40 kOe applied parallel to the c-axis. Modified coherence length model introduced by Rydh, et al. has given to prove consistenly description with the vortex glass behavior by assigning the value of critical exponent glass ( s ), namely 4 ,7 and 2,0 respectively for the corresponding crystals. Besides, curve scaling with this model resulted in the value of pinning parameter ( fi) respectively 0,45 and 0,54 for both crystal.
