摘要: Abstract Polarised neutron scattering with polarisation analysis has been used to obtain a unique measurement of the paramagnetic fluctuations in iron at temperatures between 1273 and 1573 K. The results clearly demonstrate almost complete ferromagnetic correlation over distances up 15 A. average moment per atom taking part giving rise is about 1.3μ B . These findings should lead better understanding paramagnetism metals.
