Pressure induced spin crossover in disordered α-LiFeO2
Samar Layek, Eran Greenberg, Weiming Xu +4
Structural, magnetic and electrical-transport properties of α-LiFeO2, crystallizing in the rock salt structure with random distribution of Li and Fe ions, have been studied by sync…
Phonon study of rhombohedral BS under high pressure
Kirill A. Cherednichenko, Petr S. Sokolov, Aleksandr Kalinko +4
Raman spectra of rhombohedral boron monosulfide (r-BS) were measured under pressures up to 34 GPa at room temperature. No pressure-induced structural phase transition was observed,…
Combining high pressure and coherent diffraction: a first feasibility test
D. Le Bolloc'h, J. P. Itié, A. Polian +1
We present a first experiment combining high pression and coherent X-ray diffraction. By using a dedicated diamond anvil cell, we show that the degree of coherence of the X-ray bea…
High-pressure study of X-ray diffuse scattering in ferroelectric perovskites
Sylvain Ravy, Jean-Paul Itie, Alain Polian +1
We present a high-pressure x-ray diffuse scattering study of the ABO ferroelectric perovskites BaTiO_3 and KNbO_3. The well-known diffuse lines are observed in all the phases s…
Magnetovolume instabilities in the pressure dependence of the K-edge circular dichroism of Fe3C Invar particles
E. Duman, M. Acet, E. F. Wassermann +4
The p-electrons of carbon in the interstitial compound Fe3C hybridize with the Fe d-band and enhance the valence electron concentration of Fe from 8 to 8.67. At this concentration,…
High Pressure X-Ray Diffraction Study of UMn2Ge2
Vasudeva Siruguri, S. K. Paranjpe, P. Raj +3
Uranium manganese germanide, UMn2Ge2, crystallizes in body-centered tetragonal ThCr2Si2 structure with space group I4/mmm, a = 3.993A and c = 10.809A under ambient conditions. Ener…
