Spin dynamics on the frustrated Fe7 molecular cluster
Fe7 is a magnetic cluster formed by two Fe(III) triangles bridged together by a Fe(III) ion. The antiferromagnetic exchange interaction within the two triangles makes the system... -
Evolution of the electronic structure and of the magnetic correlations in Sr2...
We plan to investigate by means of longitudinal and zero field muSR the modifications induced by (Zn,Mg) for Cu substitution in the spin correlations of Sr2CuO2Cl2, a... -
muSR in S=1/2 frustrated magnets on a square lattice
We plan to study by means of zero and longitudinal field muSR the static and dynamic magnetic properties of SrZnVO(PO4)2, a prototype of the S=1/2 J1-J2 model on a square... -
Impurity-induced frustration in La2CuO4
We plan to investigate by means of zero-field muSR the doping dependence of the sublatticemagnetization in La2Cu1-xZnxO4 and in La2Cu1-xMgxO4. In both systems Cu2+ S=1/2 spins... -
Muon-spin rotation study of the in-plane magnetic penetration depth of \refraof
This is an extention of the previous proposal (RB920385), which was awarded 7 days.The experiment has not been performed yet (scheduled in November), but we forsee... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -
muSR in Rare-earth doped Phenanthrene Superconductors
We plan to perform transverse field and zero-field μSR experiments to investigate the temperature dependence of the relaxation rate in the superconducting phase of... -
Study of low dynamics in the normal phase of iron based superconductors
Since the discovery of the iron-pnictides superconductors most of the efforts has been devoted to the study of the fundamental questions concerning the coexistence of magnetism... -
Tunneling and relaxation of the magnetization in Mn6 single molecule magnet
The Mn6 single molecule magnet shows to date the highest anisotropy barrier for a transition metal cluster. Low lying excited states in the energy level diagram of the molecule... -
Studies of the Strongly Correlated Metal Yb4LiGe4
The intermetallic family R5T4 (R = rare earth, T = Si or Ge) exhibit a wide range of magnetic phenomena (eg., magnetic order, GMR, and enhanced magnetocaloric effect) which are...
