Abstract

In article number 1703963, Alejandro G. Roca, Josep Nogués, and co-workers report the magnetic structure and properties of zinc blende and wurtzite CoO nanoparticles. Both phases are antiferromagnetic, although the wurtzite-CoO presents a complex structure with a second type order along the c-axis, but an incommensurate order along the y-axis. In addition, the overall magnetic properties are overwhelmed by the uncompensated spins, which confer the system a ferromagnetic-like behavior even at room temperature.
