Size-dependent passivation shell and magnetic properties in antiferromagnetic/ferrimagnetic core/shell MnO nanoparticles.
The magnetic properties of bimagnetic core/shell nanoparticles consisting of an antiferromagnetic MnO core and a ferrimagnetic passivation shell have been investigated. It is found that the phase of the passivation shell (gamma-Mn(2)O(3) or Mn(3)O(4)) depends on the size of the nanoparticles. Structural and magnetic characterizations concur that while the smallest nanoparticles have a predomina...
متن کاملSynthesis and size-dependent crystallization of colloidal germanium telluride nanoparticles†‡
Colloidal nanocrystals have long been used to study the dependence of phase stability and transitions on size. Both structural phase stability and phase transitions change dramatically in the nanometre size regime where the surface plays a significant role in determining the overall energetics of the system. We investigate the solid–solid phase transformation of crystallization in amorphous GeT...

A myriad of core/shell nanoparticles (NPs) have been developed and studied in the last decades aiming at the increase of functionality, stability, dispersibility, biocompatibility, and specific targeting, for instance.1 Shells can also interact synergetically with the core by changing lattice parameters, resulting in strain-engineered materials with tuned, improved, and new properties.2,3 This ...
متن کاملOne-dimensional single-crystalline Mn3O4 nanostructures with tunable length and magnetic properties of Mn3O4 nanowires.
A facile, solution-phase route to mass fabrication of one-dimensional single crystalline Mn(3)O(4) nanowires with a unique core/sheath heteronanostructure, controlled aspect ratios, and narrow diameter distribution was reported. The single crystalline Mn(3)O(4) nanowires have considerably large coercivities (H(C) > 1 T) at low temperatures.
