We report the valley-selective interlayer conduction of SrMnBi(2) under in-plane magnetic fields. The c-axis resistivity of SrMnBi(2) shows clear angular magnetoresistance oscillations indicating coherent interlayer conduction. Strong fourfold variation of the coherent peak in the c-axis resistivity reveals that the contribution of each Dirac valley is significantly modulated by the in-plane fi...

MnSi is a weak itinerant helimagnet with a relatively low order magnetic moment. Temperature dependance of resistivity shows that it enters non-Fermi liquid state above a critical pressure pc which remains to be understood. The observed partial magnetic order above pc indicates novel metallic state. Here, Fermi liquid and non-Fermi liquid theories are discussed with the main focus on the temper...

Magnetotransport measurements are performed on an aluminum thin film grown on a GaAs substrate. A crossover from electron- to hole-dominant transport can be inferred from both longitudinal resistivity and Hall resistivity with increasing the perpendicular magnetic field B. Also, phenomena of localization effects can be seen at low B. By analyzing the zero-field resistivity as a function of temp...

Artificial resistivity is included in Smoothed Particle Magnetohydrodynamics simulations to capture shocks and discontinuities in the magnetic field. Here we present a new method for adapting the strength of the applied resistivity so that shocks are captured but the dissipation of the magnetic field away from shocks is minimised. Our scheme utilises the gradient of the magnetic field as a shoc...

Magnetization and resistivity measurements have been carried out on the equiatomic ternary compound NdNiSn in the temperature range 2 200K. The compound crystallizes in the orthorhombic CeNiSn-type structure with space group Pna21. Magnetic susceptibility shows a distinct feature at TN = 3 K (Néel temperature), typical of a phase transition from an antiferromagnetic to paramagnetic state. In th...

The present information technology is based on electron transport and magnetism. Magnetism has been most successful as high-density storages such as hard disks. In magnetic storages, read-out mechanism of the information had so far several significant developments. The oldest idea of detecting magnetic information would be to use Faraday’s induction law by scanning a read head (a coil) on the s...

In magnetic resonance electrical impedance tomography (MREIT), we try to reconstruct a cross-sectional resistivity (or conductivity) image of a subject. When we inject a current through surface electrodes, it generates a magnetic field. Using a magnetic resonance imaging (MRI) scanner, we can obtain the induced magnetic flux density from MR phase images of the subject. We use recessed electrode...
