In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive... -
Investigation of Li diffusion in Li-ion battery materials by muSR
We would like to propose a continuation experiment on Li-ion battery cathode material, Li(Ni,Co)O2. In previous experiments in 2013 and 2014, we attempted muSR technique to... -
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... -

Spin dynamics in disordered La(Cr1/3Mn1/3Fe1/3)O3 perovskite.
Disorder of magnetic cations usually suppresses long-range spin order: the Curie or Néel temperature drops rapidly, and a spin glass state often results at high disorder levels.... -
Spin dynamics in pyrochlore Nd2Mo2O7
Most of Nd-pyrochlores show all-in-all-out long-ranged order ground state at low temperatures. Recently unconventional slow spin dynamics are reported in the paramagnetic state... -
