abstract = {Using a combination of neutron diffraction with XYZ
polarization analysis and magnetization measurements, the
noncollinear magnetism in nanosized cobalt chromite, a
potential multiferroic material, is revealed. For
noninteracting 26.9(1) nm nanoparticles, a bulklike behavior
is identified, including a ferrimagnetic Curie temperature
of 99 K and a transition to the spin spiral magnetic phase
at 27 K with a temperature-dependent, incommensurate
propagation vector. A lock-in transition towards a
commensurate propagation vector is not observed. Much
smaller, 3.1(2) nm, nanoparticles reveal a strong cluster
glass behavior, characterized by ferrimagnetic behavior
below the Curie temperature of 43 K and a transition to
asperomagnetic behavior at 18 K, with the absence of any
magnetic reflections at a base temperature of 5 K.},
