Journal ArticleDOI

TL;DR: In this paper, it was shown that the core of a spinel has a canted structure and the canting angle increases with grain size reduction due to the magnetocrystalline anisotropy introduced by the occupancy of the ions in the tetrahedral sites.
Journal ArticleDOI
Substrate-induced magnetic ordering and switching of iron porphyrin molecules.
Heiko Wende,Heiko Wende,Matthias Bernien,J. Luo,C. Sorg,N. Ponpandian,J. Kurde,J. Miguel,Marten Piantek,Xiaoying Xu,Ph. Eckhold,Wolfgang Kuch,K. Baberschke,Pooja M. Panchmatia,Biplab Sanyal,Peter M. Oppeneer,Olle Eriksson +16 more
TL;DR: The Fe magnetic moment can be rotated along directions in plane as well as out of plane by a magnetization reversal of the substrate, thereby opening up an avenue for spin-dependent molecular electronics.
Journal ArticleDOI
Electrical conductivity and dielectric behaviour of nanocrystalline NiFe2O4 spinel
TL;DR: In this paper, the activation energy for the grain and grain boundary conduction and its variation with grain size have been reported and the conduction mechanism is found to be due to the hopping of both electrons and holes.
Journal ArticleDOI
Magnetic properties of nanostructured ferrimagnetic zinc ferrite
C. N. Chinnasamy,A. Narayanasamy,N. Ponpandian,Kamanio Chattopadhyay,H Guérault,Jean-Marc Greneche +5 more
TL;DR: In this paper, the average grain size and the root mean square strain were estimated from the x-ray diffraction line broadening, and the lattice parameter initially decreases slightly with milling and it increases with further milling.
Journal ArticleDOI
Shape evolution of perovskite LaFeO3 nanostructures: a systematic investigation of growth mechanism, properties and morphology dependent photocatalytic activities
TL;DR: In this article, shape evolution of nanostructured LaFeO3 with fascinating morphologies like cubes, rods and spheres was successfully synthesized by a facile and environmentally friendly hydrothermal process.
