From chessboard of bipolarons of size 4a in cubic La7/8Sr1/8MnO3 to stripes of the same bipolarons in layered high Tc cuprates
Martine Hennion, Alexandre Ivanov, Claudine Lacroix +1
The compound La1-xSrxMnO3 exhibits a charge order (CO) state at and , which recalls the CO state with a decrease in the temperature of the superconducting…
Graphene in periodically alternating magnetic field: unusual quantization of the anomalous Hall effect
M. Taillefumier, V. K. Dugaev, B. Canals +2
We study the energy spectrum and electronic properties of graphene in a periodic magnetic field of zero average with a symmetry of triangular lattice. The periodic field leads to f…
Ordering in the pyrochlore antiferromagnet due to Dzyaloshinsky-Moriya interactions
M. Elhajal, B. Canals, R. Sunyer i Borrell +1
The Heisenberg nearest neighbour antiferromagnet on the pyrochlore (3D) lattice is highly frustrated and does not order at low temperature where spin-spin correlations remain short…
Green's function approach to the magnetic properties of the kagome antiferromagnet
B. H. Bernhard, B. Canals, C. Lacroix
The Heisenberg antiferromagnet is studied on the kagomé lattice by using a Green's function method based on an appropriate decoupling of the equations of motion. Thermodyna…
Classical heisenberg antiferromagnet away from the pyrochlore lattice limit: entropic versus energetic selection
C. Pinettes, B. Canals, C. Lacroix
The stability of the disordered ground state of the classical Heisenberg pyrochlore antiferromagnet is studied within extensive Monte Carlo simulations by introducing an additional…
Theory of proximity effect in superconductor/ferromagnet heterostructures
A. Bagrets, C. Lacroix, A. Vedyayev
We present a microscopic theory of proximity effect in the ferromagnet/superconductor/ferromagnet (F/S/F) nanostructures where S is s-wave low-T_c superconductor and F's are layers…
