Abstract
Spatial distribution of the trapped magnetic flux density in Y1Ba2Cu3O7-δ is measured at T=4.2 K and 77 K with the GaAs Hall device as a magnetic sensor. Experimental results show that the magnetic flux density inside the sample is almost constant spatially, and suggest that superconducting grains are coupled with each other very weakly in the present sample.Keywords
