Description:
(abstract)The coercive force (field) of Neodymium (Nd) magnets (Nd₂Fe₁₄B) is often enhanced by adding dysprosium (Dy), particularly at high temperatures. To better understand the magnetic properties of Dy-substituted systems and the underlying mechanisms of coercivity enhancement, it is essential to investigate both the thermodynamic properties and dynamic behavior of (Nd₁₋ₓDyₓ)₂Fe₁₄B from a microscopic perspective. To this end, we have recently developed an atomistic modeling approach. Using atomistic models with microscopic parameters estimated from first-principles calculations, we carried out a detailed investigation of the thermodynamic properties and dynamical features of (Nd₁₋ₓDyₓ)₂Fe₁₄B.
