(author)We have observed the bulk Fermi surface (FS) in an overdoped (x=0.3) single crystal of La2?xSrxCuO4 by using Compton scattering. A two-dimensional (2D) momentum density reconstruction from measured Compton profiles yields a clear FS signature in the third Brillouin zone along [100]. The quantitative agreement between density functional theory ...journal article 2012

Barbiellini, B. (author), Koizumi, A. (author), Mijnarends, P.E. (author), Al-Sawai, W. (author), Lin, H. (author), Nagao, T. (author), Hirota, K. (author), Itou, M. (author), Sakurai, Y. (author), Bansil, A. (author)We have studied the [100]-[110] anisotropy of the Compton profile in the bilayer manganite. Quantitative agreement is found between theory and experiment with respect to the anisotropy in the two metallic phases (i.e., the low temperature ferromagnetic and the colossal magnetoresistant phase under a magnetic field of 7 T). Robust signatures of...journal article 2009
