摘要
The Yb-170 high pressure Mossbauer-effect technique has been used to investigate on a microscopic level the ground state properties of the ferromagnetic (FM) Kondo-Iattice compound YhNiSn. Unlike general expectations, we find for 0 less than or equal to p less than or equal to 3 GPa a stable moment behavior while T-C is enhanced to its maximum value. For p > 3 GPa we observe a gradual change of the FM state to a complex magnetic ground state, This is suggested to be due to a volume dependent competition between the anisotropy of the magnetic exchange interaction and the crystal electric field anisotropy.
