Tunneling of the Mn12-acetate spin cluster
Wei bao, R. A. Robinson, J. R. Friedman +3
The term in spin Hamiltonian, which determines the quantum tunneling rate in Mn12, is measured with neutron scattering. It is much smaller than previously reported values. This may…

Detection of a Schroedinger's Cat State in an rf-SQUID
Jonathan R. Friedman, Vijay Patel, W. Chen +2
We present experimental evidence for a coherent superposition of macroscopically distinct flux states in an rf-SQUID. When the external flux Phi_x applied to the SQUID is near 1/2…
