Cis-[Ni(μ-ox)(H2O)2]∞: Metal organic coordination polymer assembled by oxalate ligand: Structural and magnetic characterization
Verónica Paredes-García,I. Rojas,Diego Venegas-Yazigi,Evgenia Spodine,Jackson A. L. C. Resende,Maria G. F. Vaz,Miguel A. Novak +6 more
TL;DR: In this article, the structure and magnetic characterization of the one dimensional catena cis-[Ni(μ-ox)(H2O)2]∞ (1) was obtained by solvothermal synthesis.
Journal ArticleDOI

Paulo C. Morais,B.M. Lacava,Andris F. Bakuzis,L.M. Lacava,Luciano P. Silva,Ricardo Bentes Azevedo,Zulmira G. M. Lacava,N. Buske,Wallace C. Nunes,Miguel A. Novak +9 more
TL;DR: In this paper, atomic force microscopy (AFM) and magnetization measurements were used to unfold the particle-size polydispersity profile of a magnetite-based magnetic fluid sample.
Journal ArticleDOI
Dynamic effects in one dimensional A'3ABO6
M. Costes,Jean-Marc Broto,Bertrand Raquet,H. Rakoto,Miguel A. Novak,J.P. Sinnecker,S. Soriano,W.S.D. Folly,A. Maignan,Vincent Hardy +9 more
TL;DR: In this article, the authors studied polycrystalline Sr3NiIrO6 and Ca3CoIo6 compounds which exhibit at low temperatures a frozen state with notable dynamic effects that can be attributed to the low-dimensionality character.
Journal ArticleDOI
Dynamic behavior of superparamagnetic iso-oriented magnesioferrite nanoparticles
TL;DR: In this paper, the authors present some dynamic magnetic properties of this system and its relation with the evolution of the average particle sizes with annealing time, and present a model of the system formed by Magnesioferrite (MgFe2O4) nanoparticles precipitated in dilute solid solutions of iron in MgO (magnesiowustite).
Journal ArticleDOI
