Size effect for exchange interactions within Fe–Pd nanoparticles
Source abstract
Abstract
The aim of this research is to calculate the exchange coupling constants within binary magnetic nanoparticles. An Fe–Pd magnetic system with nanoparticles in range of 5–50 nm in diameter is chosen for this purpose since it undergoes different phase transitions and its magnetic properties vary under external influences. Atomic ordering and external pressure influences are investigated for Fe–Pd compounds of different compositions.
