Magnetic ordering in UCu2Si2 at high pressure

Physica B Condensed Matter (Impact Factor: 1.28). 04/2008; 403:940-942. DOI: 10.1016/j.physb.2007.10.279

ABSTRACT We have performed resistivity measurements as a function of applied pressure to 2.0 GPa on a single crystal of UCu2Si2. We find that the ambient pressure magnetic ordering temperature of 100 K, and the low-temperature ordering at 50 K, both decrease gradually in a manner consistent with itinerant magnetism. The results will be compared to previous measurements on UCu2Ge2.

    ABSTRACT: The slow acceptance by the scientific community of only ferromagnetic ordering below TC in UCu2Ge2, and the general acceptance of the same magnetic situation in UCu2Si2, both with the BCT ThCr2Si2-type crystallographic structure, are reviewed chronologically. Observations by neutron diffraction on annealed polycrystalline samples of UCu2Ge2 have finally overcome many conclusions of antiferromagnetic (AF) ordering at low temperatures (LT), deduced from the magnetization overlooking the ferromagnetic domain structure. Observations by magnetization measurements on Cu-flux-grown UCu2Si2 single crystals, claiming 'a 50 K AF transition below the 100 K ferromagnetic transition', published recently in this journal (2003 J. Phys.: Condens. Matter 15 S1917), are shown to have been misinterpreted by omitting any reference to ferromagnetic domain structure. Comments are made on other features disputing the LT ferromagnetism of UCu2Si2.

    ABSTRACT: Uranium manganese germanide, UMn2Ge2, crystallizes in body-centered tetragonal ThCr2Si2 structure with space group I4/mmm, a=3.993Å and c=10.809Å under ambient conditions. Energy dispersive X-ray diffraction was used to study the compression behavior of UMn2Ge2 in a diamond anvil cell. The sample was studied up to static pressure of 26GPa and a reversible structural phase transition was observed at a pressure of 16.1GPa. Unit cell parameters were determined up to 12.4GPa and the calculated cell volumes were found to be well reproduced by a Murnaghan equation of state with K0=73.5GPa and K′=11.4. The structure of the high-pressure phase above 16.0GPa is quite complicated with very broad lines and could not be unambiguously determined with the available instrument resolution.

    ABSTRACT: We studied the electronic state of UGa3 by measuring the electrical resistivity under pressure. When pressure is applied to UGa3, the Néel temperature TN = 67 K decreases steeply and becomes zero around 2.6 GPa. Correspondingly, the coefficient A in the electrical resistivity rho = rho0 + AT2, which is characteristic for Fermi liquid, increases steeply with increasing pressure. Around a magnetic quantum critical point of 2.6 GPa, a non-Fermi-liquid behaviour is found, showing a linear T-dependence of the resistivity, although the Fermi-liquid behaviour recovers above 4 GPa and the A-value decreases with increasing pressure. Furthermore, a resistivity drop, which might be related to superconductivity, was found below 0.3 K at 1.5 GPa, where the residual resistivity rho0 has a maximum.
