A.Ritter, C.El pdf del artículo es la versión pre-print.The structural, electronic and magnetic properties of TbMn1−xCoxO3 (0.1 ≤ x ≤ 0.9) compounds are reported. The samples are isostructural to TbMnO3 adopting the orthorhombic distorted perovskite structure (Pbnm), except for x = 0.4, 0.5 and 0.6, where an ordered double perovskite structure (P21/n) is found. X-ray absorption spectra at the Mn and Co K edges show an incomplete charge transfer between Mn and Co atoms yielding a mixed valence state Mn3+/Mn4+ and Co3+/Co2+ for the whole series. Neutron powder diffraction measurements show the development of a ferromagnetic ground state for the intermediate compositions (0.3 ≤ x ≤ 0.6) indicating that the ferromagnetic superexchange Mn4+–O–Co2+ interaction is the strongest among a wide set of competitive interactions. The ferromagnetic ordering is, however, not fully achieved and coexists with glassy magnetic properties. With increasing concentration of Co (x ≥ 0.7) the long range ordering vanishes and only a glassy magnetic behavior with slow dynamics is found. These properties could be related to the existence of magnetically inhomogeneous small clusters arising from competitive magnetic interactions.Financial support from the Spanish MICINN (projects FIS08-03951 and MAT2007-61621) and DGA (CAMRADS) is acknowledged.Peer ReviewedInstitute of Physics Publishing2013201320122013info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/73508reponame:DIGITAL.CSIC.
