Resonant tunnelling and quenching of tunnel splitting in Wess-Zumino nanospin systems
Soo-Young Lee, Sahng-Kyoon Yoo
We investigate the energy spectrum of the biaxial spin systems with magnetic field along the hard anisotropy axis by using the complex periodic orbit theory. All important features…

Geometrical phase effects in biaxial nanomagentic particles
Sahng-Kyoon Yoo, Soo-Young Lee
The oscillation of tunnel splitting are obtained by geometrical analysis of the topological Wess-Zumino phase on the basis of tunneling paths in biaxial nanomagnetic particles with…
