Phys. Rev. B 79, 094420 (2009) [5 pages]Neutron scattering study of the competing magnetic correlations in La0.85Sr0.15CoO3Received 9 September 2008; revised 24 December 2008; published 20 March 2009 The nature of the competing ferromagnetic and incommensurate spin correlations in the spin-glass phase of La0.85Sr0.15CoO3 has been investigated by various neutron scattering techniques. Spin-polarized scattering indicates that the observed incommensurate peaks are dominantly magnetic in nature. Magnetic field experiments show that a field applied perpendicular to the short-range ordering wave vector destroys the incommensurate correlations and induces long-range ferromagnetic order. However, even for fields up to 7 T, short-range ferromagnetic correlations still coexist with the long-range ordered regions. © 2009 The American Physical Society URL:
