AbstractA formula to evaluate the entanglement in a one-dimensional ferrimagnetic system is derived. Based on the formula, we find that the thermal entanglement in a small size spin- 1/2 and spin- s ferrimagnetic chain is rather robust against temperature, and the threshold temperature may be arbitrarily high when s is sufficiently large. This intriguing result answers unambiguously a fundamental question: "Can entanglement and quantum behavior in physical systems survive at arbitrary high temperatures?" © 2006 The American Physical Society.
