Wavelength dependent negative and positive persistent photoconductivity in Sn delta-doped GaAs structures

V. A. Kulbachinskii, V. G. Kytin, A. V. Golikov +5

The photoconductivity of GaAs structures delta-doped by Sn has been investigated for wavelengths lambda= 650-1200 nm in the temperature interval T= 4.2-300 K. The electron densitie…

Search for a quantum phase transition in U(Pt_(1-x)Pd_x)_3

M. J. Graf, R. J. Keizer, A. de Visser +1

Pd in U(Pt_{1-x}Pd_x)_3 suppresses the superconducting T_c to 0 K at critical concentration x_c of 0.007 and induces a conventional AFM state for x > x_c. The resistivity below 1 K…

Resistivity of non-Fermi liquid U2Pt2In under pressure

P. Estrela, T. Naka, A. de Visser +3

Non-Fermi liquid behaviour in single-crystalline U2Pt2In has been studied by means of resistivity experiments (I||c) under hydrostatic pressure (P<1.5 GPa). At ambient pressure the…

Magnetism in heavy-fermion U(Pt,Pd)3 studied by mSR

R. J. Keizer, A. de Visser, A. A. Menovsky +5

We report mSR experiments carried out on a series of heavy-electron pseudobinary compounds U(Pt1-xPdx)3 (x<=0.05). For x<=0.005 the zero-field muon depolarisation is described by t…

Neutron-diffraction study of the evolution of antiferromagnetic order in UPt3 doped with Pd

R. J. Keizer, A. de Visser, A. A. Menovsky +3

Neutron-diffraction experiments have been carried out on U(Pt1-xPdx)3 single crystals (x<= 0.05). The small-moment antiferromagnetic order (SMAF) reported for pure UPt3 is robust u…

Suppression of Superconductivity in Single Crystals of UPt_3 by Pd Substitution

M. J. Graf, R. J. Keizer, A. de Visser +2

The suppression of superconductivity by substitution effects has been measured in high quality single crystals of U(Pt_{1-x} Pd_x)_3 with 0 <= x <= 0.002. While the superconducting…
