Item Open Access Room-temperature scanning Hall probe microscope (RT-SHPM) imaging of garnet films using new high-performance InSb sensors(IEEE, 2002) Oral, Ahmet; Kaval, Murat; Dede, Münir; Masuda, H.; Okamoto, A.; Shibasaki, I.; Sandhu, A.The room-temperature scanning Hall probe microscopy (RT-SHPM) imaging of garnet films using high-performance InSb sensors was discussed. The high-performance InSb micro-Hall sensors were fabricated by optical lithography. It was found that the room-temperature noise figure of the InSb sensors was 6-10 mG/√Hz, which was an order of magnitude better than GaAs-AlGaAs two-dimensional electron gas sensors.Item Open Access RT-SHPM imaging of permalloy microstructures and garnet films using new high performance INSB sensors(IEEE, 2002) Oral, Ahmet; Kaval, Murat; Dede, Münir; Sandhu, A.The room temperature scanning Hall probe microscopy (RT-SHPM) imaging of permalloy microstructures and garnet films was discussed. The high performance InSb Hall sensors were used for this purpose. It was shown that the InSb Hall probes were highly sensitive and low noise alternatives to GaAs sensors for RT-SHPM.
