A sub-micron room temperature scanning Hall probe microscope (RT-SHPM) was used for real-time imaging of surface magnetic domains of floppy disks, Sr ferrite magnets and Bi-substituted iron garnets placed in large external bias fields. Domain wall nucleation was observed in the garnets where bubble lattices expanded, collapsed and transformed into stripe domains in cyclic bias fields. Evolution of RT-SHPM images was compared with conventional vibrating sample magnetometer measurements.

Room temperature scanning Hall probe microscopy using GaAs/AlGaAs and Bi micro-hall probes Sandhu, A; Masuda, H; Oral, Ahmet; Bending, S.J; Yamada, A; Konagi, M (2002-08-12) A room temperature scanning Hall probe microscope system utilizing GaAs/AlGaAs and bismuth micro-Hall probes was used for magnetic imaging of ferromagnetic domain structures on the surfaces of crystalline thin film garnets and permanent magnets. The Bi micro-Hall probes had dimensions ranging between 0.25 and 2.8 mum(2) and were fabricated using a combination of optical lithography and focused ion beam milling. The use of bismuth was found to overcome surface depletion effects associated with semiconducting...
Room temperature scanning micro-Hall probe microscopy under extremely large pulsed magnetic fields Sandhu, A; Masuda, H; Oral, Ahmet (2003-09-01) The versatility of a room-temperature scanning Hall probe microscope system with an integrated minicoil capable of generating pulsed magnetic fields up to 2.9 T was demonstrated by imaging magnetic structures on the surface of 1.4-MB floppy disks and demagnetized strontium ferrite permanent magnets. Vibration isolation between the sample and minicoil was achieved by using a combination of quartz glass plates and silicone gel layers and enabled extremely fast measurements under fields as high as 2.9 T, witho...
Room temperature sub-micron magnetic imaging by scanning Hall probe microscopy SANDHU, ADARSH; MASUDA, HİROSHİ; Oral, Ahmet; BENDİNG, SİMON J (IOP Publishing, 2001-06-01) An ultra-high sensitive room temperature scanning Hall probe microscope (RT-SHPM) system incorporating a GaAs/AlGaAs micro-Hall probe was used for the direct magnetic imaging of localized magnetic field fluctuations in very close proximity to the surface of ferromagnetic materials. The active area, Hall coefficient and field sensitivity of the Hall probe were 0.8 mum x 0.8 mum, 0.3 Omega /G and 0.04G/root Hz, respectively. The use of a semiconducting Hall probe sensor enabled measurements in the presence of...
Room temperature scanning micro-Hall probe microscope imaging of ferromagnetic microstructures in the presence of 2.5 Tesla pulsed magnetic fields generated by an integrated mini coil Sandhu, A; Masuda, H; Oral, Ahmet (2002-12-01) A unique magnetic imaging system comprising of a room temperature scanning Hall probe microscope with an integrated mini-coil capable of generating pulsed magnetic fields up to 2.5 Tesla (width of 3 ms) was developed for the direct and non-invasive magnetic imaging of ferromagnetic micro-domains in the presence of extremely large external pulsed magnetic fields without adverse vibrational disturbance of the sample during measurements. The system was successfully used for magnetic imaging of the erasure proc...
Magnetic imaging of ferromagnetic domains by room temperature scanning hall probe microscopy using GaAs/AlGaAs and bismuth micro-hall probes Sandhu, A.; Masuda, H.; Oral, Ahmet; Bending, S.J.; Inushima, T. (2002-01-01) Heterostructure GaAs/AlGaAs and bismuth (Bi) micro-Hall probes were integrated into a room temperature scanning Hall probe microscope system (RT-SHPM) for imaging localized magnetic fluctuations at the surfaces of floppy disks, crystalline garnet thin films, and strontium ferrite permanent magnets. At a drive current of 800 μA the sensitivity of the Bi micro-probes was 0.38 G/√ Hz and comparable with the GaAs/AlGaAs probes. Bi nano-Hall probes with an active region of 200 nm × 200 nm were fabricated by focu...
