Graphene micro-Hall probes were developed for a scanning Hall probe microscope system and used for the direct magnetic imaging domains of demagnetized NdFeB permanent magnet for the first time. The Hall coefficient and minimum magnetic field resolution of graphene Hall probes at 1 kHz were found to be 0.18 Omega/G and 0.20 G/root Hz for a drive current of 3 mu A at room temperature in vacuum. The magnetic domains in NdFeB demagnetized magnet were observed at 300K, 126K and 3K successfully.

50 nm Hall sensors for room temperature scanning Hall probe microscopy SANDHU, ADARSH; KUROSAWA, KOUİCHİ; DEDE, MUNIR; Oral, Ahmet (2004-02-01) Bismuth nano-Hall sensors with dimensions similar to50 nm x 50 nm were fabricated using a combination of optical lithography and focused ion beam milling. The Hall coefficient, series resistance and optimum magnetic field sensitivity of the sensors were 4 x 10(-4) Omega/G 9.1 kOmega and 0.8 G/ rootHz, respectively. A 50 nm nano-Bi Hall sensor was installed into a room temperature scanning Hall probe microscope and successfully used for directly imaging ferromagnetic domains of low coercivity garnet thin films.
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...
Nano and micro Hall-effect sensors for room-temperature scanning hall probe microscopy SANDHU, A; OKAMOTO, A; SHİBASAKİ, I; Oral, Ahmet (2004-06-01) GaAs/AlGaAs two-dimensional electron gas (GaAs-2DEG) Hall probes are impractical for sub-micron room-temperature scanning Hall microscopy (RT-SHPM), due to surface depletion effects that limit the Hall driving current and magnetic sensitivity (B in). Nano and micro Hall-effect sensors were fabricated using Bi and InSb thin films and shown to be practical alternatives to GaAs-2DEG probes for high resolution RT-SHPM. The GaAs-2DEG and InSb probes were fabricated using photolithography and the Bi probes by opt...
Direct magnetic imaging of ferromagnetic domain structures by room temperature scanning hall probe microscopy using a bismuth micro-hall probe SANDHU, ADARSH; MASUDA, HİROSHİ; Oral, Ahmet; BENDİNG, SİMON J (IOP Publishing, 2001-05-15) A bismuth micro-Hall probe sensor with an integrated scanning tunnelling microscope tip was incorporated into a room temperature scanning Hall probe microscope system and successfully used for the direct magnetic imaging of microscopic domains of low coercivity perpendicular garnet thin films and demagnetized strontium ferrite permanent magnets. At a driving current of 800 muA, the Hall coefficient, magnetic field sensitivity and spatial resolution of the Bi probe were 3.3 x 10(-4) Omega /G, 0.38 G/root Hz ...
Room temperature scanning Hall probe microscopy of localized magnetic field fluctuations on the surfaces of magnetic recording media, permanent magnets and crystalline garnet films in external bias fields Sandhu, A; Iida, N; Masuda, H; Oral, Ahmet; Bending, SJ (2002-04-01) 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.
