Electronic structure and magnetism of La4Ni3O8 from first principles.
J. Phys. Condens. Matter 24(40) , 405502, (2012) The magnetic and electronic properties of La(4)Ni(3)O(8) are investigated by performing the full-potential linearized augmented plane wave method. The C-type antiferromagnetic spin ordering is preferred and a molecular correlated insulating state with high-sp... |

Laser action in Nd(3+)-doped lanthanum oxysulfide powders.
Opt. Express 20(21) , 23690-9, (2012) We have investigated the stimulated emission properties of Nd(3+) doped La(2)O(2)S powders at room temperature as a function of pumping energy density, excitation wavelength, and Nd(3+) ion concentration. The absolute stimulated emission energy has been measu... |

Evidence of two distinct dynamical freezing processes in single-layered perovskite La(0.7)Sr(1.3)CoO4.
J. Phys. Condens. Matter 23(33) , 336001, (2011) The static and dynamic features of magnetization have been investigated in terms of dc magnetization, ac susceptibility, and memory effects on single-layered perovskite La(0.7)Sr(1.3)CoO(4). The results indicate that short-range ferromagnetic clusters coexist... |

Origin of the low frequency radiation emitted by radiative polaritons excited by infrared radiation in planar La2O3 films.
J. Phys. Condens. Matter 25(3) , 035901, (2013) Upon excitation in thin oxide films by infrared radiation, radiative polaritons are formed with complex angular frequency ω, according to the theory of Kliewer and Fuchs (1966 Phys. Rev. 150 573). We show that radiative polaritons leak radiation with frequenc... |
