Numerical Renormalization Group calculations of the magnetization of isotropic and anisotropic Kondo impurities
M. Höck, J. Schnack
We study a Kondo impurity model with additional uniaxial anisotropy D in a non-zero magnetic field B using the Numerical Renormalization Group (NRG). The ratio g_e/g_S of electron…
Advanced quantum methods for the largest magnetic molecules
J. Schnack, J. Ummethum
We discuss modern numerical methods for quantum spin systems and their application to magnetic molecules.
Application of the finite-temperature Lanczos method for the evaluation of magnetocaloric properties of large magnetic molecules
J. Schnack, C. Heesing
We discuss the magnetocaloric properties of gadolinium containing magnetic molecules which potentially could be used for sub-Kelvin cooling. We show that a degeneracy of a singlet…
Discrete antiferromagnetic spin-wave excitations in the giant ferric wheel Fe18
J. Ummethum, J. Nehrkorn, S. Mukherjee +8
The low-temperature elementary spin excitations in the AFM molecular wheel Fe18 were studied experimentally by inelastic neutron scattering and theoretically by modern numerical me…
