Exact diagonalization studies of doped Heisenberg spin rings
J. Schnack, F. Ouchni
Motivated by magnetization studies of the "telephon number compound" Sr_14Cu_24O_41 we investigate doped Heisenberg spin rings by means of complete numerical diagonalization of a H…

Quantum Spin dynamics of the Bilayer Ferromagnet La(1.2)Sr(1.8)Mn2O7
Nic Shannon, Tapan Chatterji, Fatiha Ouchni +1
We construct a theory of spin wave excitations in the bilayer manganite La(1.2)Sr(1.8)Mn2O7 based on the simplest possible double-exchange model, but including leading quantum corr…
