Ferromagnetic Ordering

Few two-dimensional (2D) magnets have an intrinsic easy axis, which is essential for a long-range magnetic ordering for applications. Here, we show that without external magnetic fields, uniaxial strains can...

AbstractMössbauer spectra of Garfield nontronite H33a were taken at temperatures between 2·5 and 37 K under longitudinally applied magnetic fields up to 9 T. While no magnetic order was apparent in the absence of an applied field above 7 K, the application of external magnetic fields led to the induction of magnetic hyperfine splitting up to at least 19 K. Variation of the applied fields allowed determination of hyperfine fields of bulk nontronite, and indicated the bulk sample to have a Néel temperature of about 20 K. The non-ideal behaviour of this nontronite, leading to the lack of magnetic order in the absence of applied magnetic fields, is in line with the frustration of antiferromagnetic order in the octahedral sheets due to the presence of about 6% of the iron content in tetrahedral sites, although some influence of magnetic dilution cannot be excluded.

The Mossbauer studies of yttrium iron garnet (YIG) films grown on the gadolinium gallium garnet (GGG) substrate was realized for different films thickness (2.85 and 5.42 mm) at the applied external magnetic field. It is shown that the main changes in the magnetic microstructure of YIG/GGG films are occurred at magnetic field value up to 2.20 kOe. The changes of the hyperfine magnetic fields on the iron nuclei have been investigated and its isotropic component was analyzed. It was determined that the domain structure changes (in particular, the domains width enlarging) under the applied magnetic field increase with the film thickness decreasing.

Magnetic susceptibilities from 130 to 4.2 K are reported for a series of Fe(RSO3)2 compounds, where R is F, CF3, CH3, and p-CH3C6H4. The β form of Fe(CH3SO3)2 exhibits a maximum in susceptibility at approximately 22.5 K and a sharp drop in susceptibility below the maximum indicating a transition to a magnetically ordered state. None of the other compounds exhibit magnetic ordering although abnormally low magnetic moments down to 2.0 K are observed for α-Fe(CH3SO3)2. Variable-temperature Mössbauer studies on Fe(CF3SO3)2 and β- and α-Fe(CH3SO3)2 are reported and the magnitude of axial field splitting is estimated for these compounds. The first two have trigonally elongated FeO6 chromophores, whereas the third is trigonally compressed. The nature of the distortion in α-Fe(CH3SO3)2 is confirmed by magnetic perturbation Mössbauer studies. Spectra in applied fields of 4.50 and 5.63 T show a doublet–triplet pattern, with the triplet at higher energy, indicating a negative Vzz and an orbital singlet ground state.
