Dear all
For test ,I constructed a simple Ni nanowire along [001] and I want to calculate the magnetic anisotropy energy. I get the full relativistic pseudopotential and lattice constant from example 26 of espresso.But for relaxation with nanocoliin and lspinorbit switch it does'nt converge . where is the error or which paprameter must be modified?
thanks
