Stabilization of charge and orbital ordered states by antiferromagnetism in the A-site ordered YBaMn2O6 (2009)

Zhang, X. N., Lemmens, P., Nakajima, T., Ueda, Y.

We report on Raman scattering measurements of the A-site ordered YBaMn2O6 in the wide temperature range of 10-650K. Upon cooling almost all phonon modes show pronounced temperature dependencies of...

Self-energy effects and electron-phonon coupling in Fe-As superconductors (2009)

Lemmens, P., Eremin, I., Zwicknagl, G., Berger, H., Sun, G. L., ...

We report on Raman scattering experiments of the undoped SrFe2As2 and superconducting Sr0.85K0.15Fe2As2 (Tc=28K) and Ba0.72K0.28Fe2As2 (Tc=32K) single crystals. The frequency and linewidth of the B1g...

Optical phonons, spin correlations, and spin-phonon coupling in the frustrated pyrochlore magnets CdCr2O4 and ZnCr2O4 (2009)

Kant, Ch., Deisenhofer, J., Rudolf, T., Mayr, F., Schrettle, F., Loidl, A., ...

We report on infrared, Raman, magnetic susceptibility, and specific heat measurements on CdCr2O4 and ZnCr2O4 single crystals. We estimate the nearest-neighbor and next-nearest neighbor exchange...

Spectral sensitive phonon wipeout due to a fluctuating spin state in a Fe2+ coordination polymer (2009)

Gnezdilov, V., Lemmens, P., Scheib, P., Ghosh, M., Pashkevich, Yu. G., Paulsen, H., ...

Raman scattering in the spin-crossover system [Fe(pmd)(H2O){Au(CN)2}2]*H2O reveals a complex three-phase spin-state transition in contrast to earlier observations in magnetization measurements. We...

Iron pnictides: Single crystal growth and effect of doping on structural, transport and magnetic properties (2009)

Sun, G. L., Sun, D. L., Konuma, M., Popovich, P., Boris, A., Peng, J. B., ...

We demonstrate the preparation of large, free standing iron pnictide single crystals with a size up to 20 x 10 x 1 mm3 using solvents in zirconia crucibles under argon atmosphere. Transport and...

Structural and magnetic dimers in the spin-gapped system CuTe2O5 (2006)

Deisenhofer, J., Eremina, R. M., Pimenov, A., Gavrilova, T., Berger, H., Johnsson, M., ...

We investigated the magnetic properties of the system CuTe2O5 by susceptibility and electron spin resonance measurements. The anisotropy of the effective g-factors and the ESR linewidth indicates...

Unusual criticality of Cu2Te2O5Br2 under pressure (2005)

Kreitlow, J., Suellow, S., Menzel, D., Schoenes, J., Lemmens, P., Johnsson, M.

We present measurements of the magnetic susceptibility chi(T) on Cu2Te2O5Br2 under externally applied pressure. From our data we extract the pressure response of the antiferromagnetic phase...

Surveillance of human Yersinia enterocolitica infections in Belgium: 1967-1996 (1998)

Charlier, J, Lemmens, P, Delmée, M, Van Noyen, R, Verbist, Ludo; U0018552, ...

Between 1967 and 1996, > 18,700 strains of Yersinia species, excluding Yersinia pestis, were recovered in Belgium from a variety of gastrointestinal and extraintestinal sites in patients. Full...

Antimicrobial resistance and serotypes of Shigella isolates in Kigali, Rwanda (1983 to 1993): increasing frequency of multiple resistance (1997)

Bogaerts, Jan; U0008784, Munyabikali, J P, Mukantabana, B, Lemmens, P, Vandeven, J, ...

The serotype distribution and susceptibility to nine antibiotics was determined for 2491 Shigella isolates cultured in the medical laboratory of the Centre Hospitalier de Kigali, Rwanda, during 1983...

Human Salmonella and Shigella infections in Moroni, the capital of Great Comoro Island (1987-1988) (1990)

Petat, E A, Martinet, F, Lemmens, P, Ghysels, G, Vandepitte, Jozef; U0007116

Over a period of two years 98 cultures of Salmonella and 17 cultures of Shigella were isolated at the El Maarouf Hospital, Moroni, capital of the Comoros. Almost half of the isolates were from...
