Magnetic property and critical current of BiSrCaCuO system under low magnetic field
- 1. Dept. of Physics, Univ. of Science and Technology of China, Hefei, Anhui (China)
Description
The low critical field Hcl is determined by a.c.chi versus H and M versus H. For a sample of BiSrCaCuO with Tc(O) = 89 K, Hcl is equal to 17.5 Oe at 77 K. Measurement of the critical current Jc under low magnetic field shows that there is a peak on Jc-H curve at about 1 Oe due to the existence of the earth's magnetic field and the current density is very small in the BiSrCaCuO system and Jc is nearly zero when the magnetic field reaches 150 Oe. It is suggested that the pinning force is very weak in this material
