Abstract :
The stray magnetic field distributions from an isolated magnetic bubble domain of about 150-µm diameter in YFeO3are measured by a micro Hall element made of a single crystal InSb with active dimensions of 5 × 5 × 2.6 µm3. Experimental results for an isolated bubble domain show fair agreement with the theoretical ones for a cylindrical bubble domain.
