2014 The electrical resistivity (p) data as a function of temperature are reported for Pt3FexMn1-x alloys (with x = 0, 0.5, 0.6, 0.7, 0.8 and 1.0). The p(T) curve for Pt3Fe0.6Mn0.4 shows two 03C1-anomalies, one of which is attributed to the Curie temperature and the other to the transition to a heterogeneous non-colinear magnetic structure, thus favouring the hypothesis that the exchange revers...

For the high frequency application in mobile communication technology, the operating frequency is over 3GHz, hence the ferromagnetic resonance frequency (fres) of magnetic films must be over 3 GHz. In this study, FeCoHfO alloy is chosen as a promising material system for this application. Inserting an insulator (e.g., AlOx) layer into ferromagnetic layers is a good way to enhance the resistivit...

The effects of Ge partial substitution onto Si site of Er5Si4 alloy were investigated by means of thermal and electrical transport measurements. Temperature-dependent electrical resistivity (r), Seebeck coefficient (S ), and thermal conductivity (k) measurements from 7 to 300K were performed on a series of Er5Si4 xGex alloys with x varying from 0 to 2. Noticeable anomalies were observed at the ...

We observed the coexistence of superconductivity and antiferromagnetic order in the single-crystalline ternary pnictide HoPdBi, a plausible topological semimetal. The compound orders antiferromagnetically at TN = 1.9 K and exhibits superconductivity below Tc = 0.7 K, which was confirmed by magnetic, electrical transport and specific heat measurements. The specific heat shows anomalies correspon...

An analytic solution to the problem of strongly magnetized plasma flow past a smooth, conducting sphere is considered. The magnetic field is taken to be uniform at very large distances and the sphere is assumed to be unmagnetized. In addition, the flow speed is assumed to be subsonic and super-Alfvénic. It is shown that a steady state solution is possible only if the frozen-in condition can be ...

We present measurements of the magnetic susceptibility, heat capacity and electrical resistivity of Pu1−xLuxPd3, with x=0, 0.1, 0.2, 0.5, 0.8 and 1. PuPd3 is an antiferromagnetic heavy fermion compound with TN = 24 K. With increasing Lu doping, both the Kondo and RKKY interaction strengths fall, as judged by the Sommerfeld coefficient γ and Néel temperature TN . Fits to a crystal field model of...

The crystal structure and numerous normal and superconducting state properties of layered tetragonal (P4/nmm) LaFeAsO, with F-doping of  11 %, are reported. Resistivity measurements give an onset transition temperature Tc = 28.2 K, and low field magnetic susceptibility data indicate bulk superconductivity. In applied magnetic field, analysis of the resistive transition results in a critical fi...

The magnetoresistance of a granular superconductor in a strong magnetic field is considered. It is assumed that this field destroys the superconducting gap in each grain, such that all interesting effects considered in the paper are due to superconducting fluctuations. The conductance of the system is assumed to be large, which allows us to neglect all localization effects as well as the Coulom...

Dissipation range spectra for incompressible magnetohydrodynamic turbulence are derived for isotropic viscosity and resistivity . The spectra are obtained from heuristic closures of spectral transfer correlations for cases with Pm= / 1, where Pm is the magnetic Prandtl number. Familiar inertial range power laws are modified by exponential factors that dominate spectral falloff in the dissipatio...
