Magnetoresistance in the helical itinerant magnets MnSi and MnCoSi
A. E. Petrova, S. Yu. Gavrilkin, D. Menzel +2
We studied the longitudinal and transverse magnetoresistance of helical magnets, MnSi and MnCoSi, at temperatures between 1.8 and 100~K and in magnetic fields up to 9 T…
Independent determination of the two gaps by directional point-contact spectroscopy in MgB_2 single crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +4
Directional point-contact spectroscopy measurements were performed for the first time in state-of-the-art MgB_2 single crystals. The selective suppression of the superconductivity…
Evidence for pseudogap and phase-coherence gap separation by Andreev reflection experiments in Au/La_{2-x}Sr_{x}CuO_4 point-contact junctions
R. S. Gonnelli, A. Calzolari, D. Daghero +4
We present new Au/La_{2-x}Sr_{x}CuO_{4} (LSCO) point-contact conductance measures as a function of voltage and temperature in samples with 0.08 <= x <= 0.2. Andreev reflection feat…
Anomalies in the ab-plane resistivity of strongly underdoped La_{2-x}Sr_{x}CuO_{4} single crystals: possible charge stripe ordering?
R. S. Gonnelli, V. A. Stepanov, A. Morello +5
We present and discuss the results of measurements of the ab-plane resistivity of La_{2-x}Sr_{x}CuO_{4} single crystals with small Sr contents (x=0.052-0.075). The resistivity was…
