摘要: We present a study of the magnetic ground state properties β-Mn metal alloyed with Co, using neutron polarization analysis diffuse scattering cross-section. analyse structure obtained reverse Monte Carlo procedure to extract Mn-Mn spin correlations. The addition Co leads static disordered medium-range Our correlations indicates that both 8c and 12d non-equivalent lattice sites in contribute state, where previously it was thought site non-magnetic.
