Magnetic interactions and the pressure phase-diagram of CuGeO3
P. H. M. van Loosdrecht, J. Zeman, G. Martinez +3
A pressure and temperature dependent Raman study of the vibrational and spin dynamics in CuGeO3 is presented. A new low temperature, high pressure phase has been identified, and a…
(Sr/Ca)_{14}Cu_{24}O_{41} spin ladders studied by NMR under pressure
Y. Piskunov, D. Jérome, P. Auban-Senzier +5
(63)Cu-NMR measurements have been performed on two-leg hole-doped spin ladders Sr_{14-x}Ca_{x}Cu_{24}O_{41} single crystals (0-x-12) at several pressures up to the pressure domain…
Inhomogeneous ordering in weakly coupled Heisenberg chains with random bonds
M. Thede, T. Haku, T. Masuda +6
Long range magnetic ordering in the quasi-one-dimensional random-bond antiferromagnet BaCu(SiGe)O is studied in SR experiments as a function of disord…
Multiple spin-flop phase diagram of BaCu2Si2O7
V. N. Glazkov, G. Dhalenne, A. Revcolevschi +1
The quasi one-dimensional compound BaCu2Si2O7 demonstrates numerous spin-reorientation transitions both for a magnetic field applied along the easy axis of magnetization, and for a…
Universal behavior of spin-mediated energy transport in S=1/2 chain cuprates: BaCu2Si2O7 as an example
A. V. Sologubenko, H. R. Ott, G. Dhalenne +1
The thermal conductivity of the spin-1/2 chain cuprate BaCu2Si2O7 was measured along different crystallographic directions in the temperature region between 0.5 and 300 K. The ther…
AC magnetic behavior of large grain magneto-resistive La0.78Ca0.22Mn0.90Ox materials
Ph. Vanderbemden, B. Vertruyen, A. Rulmont +3
We report a detailed set of AC magnetic measurements carried out on bulk large grain La-Ca-Mn-O samples extracted from a floating zone method-grown rod. Three samples with $La_{0.7…
