Magnetotransport of single crystalline NbAs

Magnetotransport of single crystalline NbAs.

We report transport measurement in zero and applied magnetic field on a single crystal of NbAs. Transverse and longitudinal magnetoresistance in the plane of this tetragonal structure does not saturate up to 9 T. In the transverse configuration (H ∥ c, I ⊥ c) it is 230,000% at 2 K. The Hall coefficient changes sign from hole-like at room temperature to electron-like below ∼150 K. The electron c...

Magnetotransport in Tb2Fe17 single crystals

We have performed measurements of the Hall effect, electrical resistivity, and magnetization on Tb2Fe17 single crystals in the 5 to 300 K temperature range, and in magnetic fields of up to 5 T. We find that the anomalous Hall effect of this ferromagnet depends strongly on the magnetization direction relative to the crystal axes. The AHE resistivity, measured with an applied magnetic field H per...

Fundamental magnetotransport anisotropy in R2Fe17 single crystals

We have measured the resistivity and Hall effect of R2Fe17 (R = Y, Tb, and Gd) single crystals in the temperature T range 4 < T < 300 K and applied magnetic fields of up to 9 T. The anomalous Hall effect (AHE) is very anisotropic in these ferromagnets. The AHE resistivity, measured with an applied magnetic field H perpendicular to the c axis, is very large and varies quite linearly with the lon...

Magnetotransport properties of CrO2 films down to single-grain sizes

Single-crystalline LaB6 nanowires.

Lanthanum hexaboride nanowires produced by chemical vapor deposition are single-crystalline and grown along the [111] direction. Streaks appearing in the electron diffraction spots indicate the lateral direction perpendicular to the nanowire growth axis.
