Abstract

We describe an experimental technique for simultaneous measurement of both the normal (B_z) and the in-plane (B_x) components of the magnetic induction field near the surface of a superconducting sample. This technique utilizes a novel design of a double-layered Hall sensor array fabricated from a GaAs/AlGaAs heterostructure containing two parallel layers of a two-dimensional electron gas. The effectiveness of this technique is demonstrated in measurements of B_x and B_z and the current distribution at the surface of a thin YBa₂Cu₃O₇ crystal.
