Macroscopic quantum effects observed in Mössbauer spectra of antiferromagnetic nanoparticles

  • Mikhail A. Chuev


The 57Fe Mössbauer spectra of antiferromagnetic nanoparticles have been measured for almost half a century and often displayed a specific (non-superparamagnetic) temperature evolution of the spectral shape which looks like a quantum superposition of well-resolved magnetic hyperfine structure and single line or quadrupolar doublet of lines with the temperature-dependent partial spectral areas. We have developed a quantum-mechanical model for describing thermodynamic characteristics of an ensemble of ideal and “uncompensated” antiferromagnetic nanoparticles with uniaxial magnetic anisotropy in the first approximation of slowly relaxing macrospins of magnetic sublattices. This model allows one to qualitatively describe the macroscopic quantum effects observed in the Mössbauer spectra and to clarify principally the difference in thermodynamic properties of ferromagnetic and antiferromagnetic particles revealed in spectroscopic measurements.
