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…
Sn delta-doping in GaAs
V. A. Kulbachinskii, V. G. Kytin, R. A. Lunin +7
We have prepared a number of GaAs structures delta-doped by Sn using the well-known molecular beam epitaxy growth technique. The samples obtained for a wide range of Sn doping dens…
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…
Superconductivity in heavy-fermion U(Pt,Pd)3 and its interplay with magnetism
R. J. Keizer, A. de Visser, M. J. Graf +2
The effect of Pd doping on the superconducting phase diagram of the unconventional superconductor UPt3 has been measured by (magneto)resistance, specific heat, thermal expansion an…
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…
Studies of superconductivity in U(Pt1-xPdx)3 for x < 0.006
M. J. Graf, R. J. Keizer, A. de Visser +1
We report measurements of the specific heat and resistivity (T < 1 K) for high quality polycrystals of U(Pt1-xPdx)3 with x < 0.006. The Tc-x phase diagram can be constructed, and s…
Thermodynamics of CeNiSn at low temperatures and in weak magnetic fields
K. A. Kikoin, M. N. Kiselev, A. S. Mishchenko +1
Detailed experimental and theoretical studies of the low-temperature specific heat, magnetic susceptibility, thermal expansion and magnetostriction of the orthorhombic compound CeN…
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…
