Magnetotransport properties of antiferromagnetic YBa2Cu3O6.25 single crystals

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 mechanisms in strongly underdoped YBa2Cu3Ox single crystals

We report magnetoresistivity measurements on strongly underdoped YBa2Cu3Ox (x56.25 and 6.36) single crystals in applied magnetic fields Hi c axis. We identify two different contributions to both in-plane Drab /rab and out-of-plane Drc /rc magnetoresistivities. The first contribution has the same sign as the temperature coefficient of the resistivity ] ln ri /]T (i5$c ,ab%). This contribution re...

La-dilution effects in antiferromagnetic TbRhIn5 single crystals

We report on measurements of temperature-dependent magnetic susceptibility, resonant x-ray magnetic scattering XRMS , and heat capacity on single crystals of Tb1−xLaxRhIn5 for nominal concentrations in the range 0 x 1. TbRhIn5 is an antiferromagnetic AFM compound with TN 46 K, which are the highest TN values along the RRhIn5 series R: rare earth . We explore the suppression of the AFM state as ...
