Ab-initio study of anisotropy and nonuniaxial anisotropy coefficients in Pd nanochains

- Anisotropy coefficients are reported for linear, ladder and zigzag chains of Pd.
- Misalignment of spin and orbital moment of Pd chains is investigated.
- Magnetics of various Pd chains are reported as a function of spin quantization axis.
- The chain axis is found to be the saddle point of energy between easy and hard axis.
- The magnetic anisotropy is highest in ladder chains of Pd than in other chains.
