		are presented and analyzed in terms of current models of charge
		conversion at a superconductor-ferromagnet interface. We investigate
		the influence of surface transparency, and study the crossover from
		ballistic to diffusive transport regime as contact size is varied.
		Application of a Nb tip to a (In,Mn)Sb sample with Curie temperature
		T-C of 5.4 K allowed the determination of spin polarization when the
		ferromagnetic phase-transition temperature is crossed. We find a
		striking difference between the temperature dependence of the local
		spin polarization and of the macroscopic magnetization, and demonstrate
		that nanoscale clusters with magnetization close to the saturated value
		are present even well above the magnetic phase-transition temperature.},

	abstract = {The systematics of the bandwidth- and filling-controlled
		metal-insulator transitions (MITs) have been investigated for R2Mo2O7
		family (R=Nd, Sm, Eu, Gd, Dy, and Ho) by infrared spectroscopy. The
		substantial role of electron correlation in driving the MIT is
		verified. With changing the R ionic radius (r) or equivalently the
		one-electron bandwidth (W), the MIT occurs in a continuous manner at
		r(c)approximate to r(R=Gd). The T=0 K gap continuously vanishes as
		Delta proportional to(r(c)-r), while at the metallic side the linear
		decrease of Drude weight is followed toward r(c). In the metallic
		compounds, some of the infrared-active phonon modes show remarkably
		large Fano asymmetry correlating with the Drude weight. These Mo-O-Mo
		bending modes strongly couple to the conduction electrons via effective
		modulation of the bandwidth. Even for r less than or similar to r(c) a
		minimal level of hole doping closes the correlation gap, for example,
		the barely insulating Gd2Mo2O7 is turned to an incoherent metal by 5%
		partial substitution of Gd3+ with Ca2+. However, even on further doping
		no coherent electronic states are formed, indicating the role of the
		disorder-induced localization effect besides the dominant correlation
		effects.},

The comparison of our experiments with recent theoretical prediction for the hydrogen welding of Au nanowires implies that a hydrogen molecule can even be incorporated in the gold nanocontact, and this hydrogen clamp is strong enough to pull a chain of gold atoms.},
