摘要

We have analyzed theoretically the photoemission spectra of the insulating compound Li2VOSiO4. Recently, this compound has been proposed as the first experimental realization of the frustrated J(1)-J(2) Heisenberg model. Although it is well known that Li2VOSiO4 is magnetically ordered in a collinear arrangement below T-N = 2.8 K, there is some controversy about the coexistence of two collinear phases above T-N. Using a generalized t-J model we have obtained a complex spectral structure that can be traced back to the underlying collinear magnetic structures. We discuss the possibility to use ARPES experiments as a way to discern among the different scenarios proposed in the literature. (c) 2007 Elsevier B.V. All rights reserved.
