Title: Magnetic Frustration Driven by Itinerancy in Spinel CoV 2O 4

Abstract

Localized spins and itinerant electrons rarely coexist in geometrically-frustrated spinel lattices. They exhibit a complex interplay between localized spins and itinerant electrons. In this paper, we study the origin of the unusual spin structure of the spinel CoV 2O 4, which stands at the crossover from insulating to itinerant behavior using the first principle calculation and neutron diffraction measurement. In contrast to the expected paramagnetism, localized spins supported by enhanced exchange couplings are frustrated by the effects of delocalized electrons. This frustration produces a non-collinear spin state even without orbital orderings and may be responsible for macroscopic spin-glass behavior. As a result, competing phases can be uncovered by external perturbations such as pressure or magnetic field, which enhances the frustration.

Figure 1 Figure 1: NC spin states in cubic CoV2O4 compared to tetragonal MnV2O4. Temperature dependence of the (111) (triangles), (220) (circles), and (002) (squares) Bragg peak intensities for CoV2O4 (a) and MnV2O4 (b) measured by neutron diffraction at HB-3A. The peak intensities of (111) and (220) above the magnetic transition temperaturemore » are fully from the nuclear structure and were subtracted. The (002) peak is not allowed from the structural symmetry and fully originated from the magnetic scattering. The background was subtracted. All the magnetic peaks observed by our neutron diffraction are instrument resolution limited besides the peak broadening caused by the structural transition for MnV2O4, and thus indicate the long range ordered magnetic moments. The strongly-reduced intensity of (002) peak in CoV2O4 indicates that only tiny amount of V spin orders, which is caused by enhanced itinerancy.« less
