Report

Neutron scattering study of a quasi-2D spin-1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure

Autor: Hong, Tao, Stock, C., Cabrera, I., Broholm, C., Qiu, Y., Leao, J. B., Poulton, S. J., Copley, J. R. D.

Publikováno v: Physical Review B 82, 184424 (2010)

We report inelastic neutron scattering study of a quasi-two-dimensional S=1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure. The spin gap {\Delta} becomes softened with the increase of the hydrostatic pressure up to P= 9.0

Autor: Goldman, A. I., Kreyssig, A., Prokes, K., Pratt, D. K., Argyriou, D. N., Lynn, J. W., Nandi, S., Kimber, S. A. J., Chen, Y., Lee, Y. B., Samolyuk, G., Leao, J. B., Poulton, S. J., Bud'ko, S. L., Ni, N., Canfield, P. C., Harmon, B. N., McQueeney, R. J.

Publikováno v: Phys. Rev. B 79, 024513 (2009)

Single crystal neutron and high-energy x-ray diffraction have identified the phase lines corresponding to transitions between the ambient-pressure tetragonal (T), the antiferromagnetic orthorhombic (O) and the non-magnetic collapsed tetragonal (cT) p

Effect of pressure on the quantum spin ladder material IPA-CuCl3

Autor: Hong, Tao, Garlea, V. O., Zheludev, A., Fernandez-Baca, J., Manaka, H., Chang, S., Leao, J. B., Poulton, S. J.

Publikováno v: Phys. Rev. B 78, 224409 (2008)

Inelastic neutron scattering and bulk magnetic susceptibility studies of the quantum S=1/2 spin ladder system IPA-CuCl3 are performed under hydrostatic pressure. The pressure dependence of the spin gap $\Delta$ is determined. At $P=1.5$ GPa it is red

Report

Pressure-induced volume-collapsed tetragonal phase of CaFe2As2 as seen via neutron scattering

Autor: Kreyssig, A., Green, M. A., Lee, Y., Samolyuk, G. D., Zajdel, P., Lynn, J. W., Bud'ko, S. L., Torikachvili, M. S., Ni, N., Nandi, S., Leao, J., Poulton, S. J., Argyriou, D. N., Harmon, B. N., Canfield, P. C., McQueeney, R. J., Goldman, A. I.

Publikováno v: Phys. Rev. B 78, 184517 (2008)

Recent investigations of the superconducting iron-arsenide families have highlighted the role of pressure, be it chemical or mechanical, in fostering superconductivity. Here we report that CaFe2As2 undergoes a pressure-induced transition to a non-mag
