© 2003 IEEE.In this paper, we describe the use of pulsed magnetic field as a well established method for producing extremely large fields but the integration of pulse coils and peripheral instrumentation with the RT-SHPM necessitates extreme care due to the adverse effects of external vibrations during continuous magnetic imaging measurements.

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...
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 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...
Induced Current Magnetic Resonance Electrical Conductivity Imaging With Oscillating Gradients
Eroglu, Hasan H.; Sadighi, Mehdi; Eyüboğlu, Behçet Murat (2018-07-01)
In this paper, induced current magnetic resonance electrical impedance tomography (ICMREIT) by means of current induction due to time-varying gradient fields of magnetic resonance imaging (MRI) systems is proposed. Eddy current and secondary magnetic flux density distributions are calculated for a numerical model composed of a z-gradient coil and a cylindrical conductor. An MRI pulse sequence is developed for the experimental evaluation of ICMREIT on a 3T MRI scanner. A relationship between the secondary ma...
Anisotropic conductivity imaging with MREIT using equipotential projection algorithm
DEĞİRMENCİ, EVREN; Eyüboğlu, Behçet Murat (2007-09-02)
Magnetic resonance electrical impedance tomography (MREIT) is a new medical imaging technique which combines boundary potential measurements of electrical impedance tomography (EIT) and internal current density distribution obtained from magnetic resonance imaging (MRI) to produce conductivity images having high spatial resolution and accuracy. In this study, a novel method of reconstructing images of anisotropic conductivity tensor distribution inside an electrically conducting subject is proposed for MREI...
