Pressure Dependence of the Magnetic Anisotropy in the 'Single-Molecule Magnet' [Mn4O3Br(OAc)3(dbm)3]

Autor: Sieber, Andreas, Chaboussant, Gregory, Bircher, Roland, Boskovic, Colette, Guedel, Hans U., Christou, George, Mutka, Hannu

Publikováno v: Physical Review B 70, 172413 (2004)

The anisotropy splitting in the ground state of the single-molecule magnet [Mn4O3Br(OAc)3(dbm)3] is studied by inelastic neutron scattering as a function of hydrostatic pressure. This allows a tuning of the anisotropy and thus the energy barrier for

Transverse Magnetic Anisotropy in Mn12-acetate: Direct Determination by Inelastic Neutron Scattering

Autor: Bircher, Roland, Chaboussant, Gregory, Sieber, Andreas, Guedel, Hans U., Mutka, Hannu

Publikováno v: Physical Review B 70, 212413 (2004)

A high resolution inelastic neutron scattering (INS) study of fully deuterated Mn$_{12}$-acetate provides the most accurate spin Hamiltonian parameters for this prototype single molecule magnet so far. The Mn$_{12}$-clusters deviate from axial symmet
