Description
We have identified Y2BaNiO5 as a new Haldane state chain compound with a magnetic excitation gap Δmin/kB of 100±5 K and Δmin/vertical stroke Jvertical stroke ∼0.3. Single crystal results of χ(T→0) reveal a splitting of the excited magnetic state. The S=1 chains have been severed in a controlled way by the substitution of Zn or Mg for Ni, and the resulting modifications of χ(T) are presented. (orig.)
