Magnetic and transport measurements have been performed in high quality YBa2Cu3O7- delta single crystals. We demonstrate for the first time that the magnetization peak line in the phase diagram of YBa2Cu3O7- delta , Hp(T) exhibits an impressive simil

Magnetotransport measurements on a clean, untwinned YBa2Cu3O7−δ single crystal show that the vortex dynamics at temperatures just below the vortex lattice melting transition are highly dependent on the type of modulation of the probing current. Wh

We present data from a.c. susceptibility and resistivity measurements in an applied d.c. magnetic field on clean detwinned YBa 2 Cu 3 O 6.92 single crystals. Our investigations have revealed an extremely sharp amplitude and frequency independent onse

The amplitude of the χ″ peak is found to be strongly temperature dependent in a wide temperature region below the melting line. We explain this effect by a crossover from a hysteretic (at low T) to non-hysteretic (at high T) mechanism of the a.c.

We present magneto-resistance data from a high quality detwinned YBa 2 Cu 3 O 7−δ single crystal, taken using the conventional four-point method with the current applied along the ab plane and the field along the c-axis. Measurements were taken in

We present magneto-resistance data for a high quality, twinned YBa2Cu3O7−δ crystal, taken with the current applied along the ab plane. The crystal was examined at a number of angles to an applied magnetic field, of up to 20T, in order to observe t

The Laki beds (Eocene) of northwestern India are thickest in the Suleiman foothills. These are correlated with the Laki of the Salt range, the Kohat district, and the Punjab.

The surface oil showings of West Pakistan occur mainly in Eocene beds, more particularly in porcellaneous limestones laid down during a transition from open-water marine to brackish-water inland sea conditions; the changing environment may have playe
