Abstract

{sup 166}Er Mössbauer spectroscopy measurements of CdEr{sub 2}S{sub 4} show a large hyperfine field (B{sub hf}) of 727.6(8) T at 5 K and clear evidence for slow paramagnetic relaxation with an energy barrier to reversal of 114(3) K. This behaviour stands in strong contrast to that of the corresponding pyrochlores (Er{sub 2}Sn{sub 2}O{sub 7} and Er{sub 2}Ti{sub 2}O{sub 7}) where no magnetic effects are seen down to 1.56 K. The clearly dynamic {sup 166}Er Mössbauer spectra and the absence of a break in the susceptibility data suggest that there is no magnetic order above 1.8 K in CdEr{sub 2}S{sub 4}.

Synthesis, structural characterization and Mössbauer study of LnV{sub 0.5}Fe{sub 0.5}O{sub 3} perovskites (Ln = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er)

Journal Article Ivashita, Flávio; Biondo, Valdecir; Bellini, Jusmar; ... - Materials Research Bulletin

Graphical abstract: Mössbauer spectra taken at 200 K for the Y(V{sub 0.5}Fe{sub 0.5})O{sub 3} orthoferrivanadate synthesized by arc-melting. Highlights: ► LnFe{sub 0.5}V{sub 0.5}O{sub 3} were synthesized by the first time for most of the rare-earth elements. ► These orthoferrivanadates crystallize metastably with the perovskite structure. ► Iron and vanadium are trivalent stabilized in these solid solutions. ► The Mössbauer quadrupolar splitting is correlated with the tolerance factor. ► Below 100 K, these perovskites undergo a crystallographic phase transformation. -- Abstract: Perovskites LnV{sub 0.5}Fe{sub 0.5}O{sub 3} (Ln = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er)more »« less

$sup 160$Dy and $sup 166$Er Moessbauer studies of concentrated and dilute rare earth dihydrides: Single-line compounds and crystal-field effects

Journal Article Stohr, J; Cashion, J - Phys. Rev., B, v. 12, no. 11, pp. 4805-4811

Mossbauer-effect measurements on the cubic intermetallic rare-earth dihydrides are reported utilizing the 86.8-keV and the 80.6-keV 2$sup +$ $Yields$ 0$sup +$ $gamma$ transitions of $sup 160$Dy and $sup 166$Er, respectively. All studies were carried out at liquid-helium temperatures on pure and dilute (with Y or Sc) paramagnetic samples. In the more concentrated alloys spin-spin (4f-4f) relaxation rates at 4.2 K are sufficiently fast to allow for the use of these systems as narrow-single-line Mossbauer sources and absorbers. Measurements on highly dilute $sup 160$Dy and $sup 166$Er impurities in YH$sub 2$ reveal the resolved paramagnetic hyperfine structure of a GAMMA$sub 7$more »« less
SrAgZn and EuAgZn with KHg{sub 2}-type structure—Structure, magnetic properties, and {sup 151}Eu Mössbauer spectroscopy

Journal Article Gerke, Birgit; Rodewald, Ute; Niehaus, Oliver; ... - Journal of Solid State Chemistry

Samples of SrAgZn and EuAgZn were synthesized by reaction of the elements in sealed tantalum crucibles. Both structures were refined on the basis of single crystal X-ray diffractometer data: KHg{sub 2}-type, Imma, a=476.7(1), b=780.9(2), c=810.1(2) pm, R{sub 1}/wR{sub 2}=0.0189/0.0119, 381 F² values for SrAg{sub 1.12}Zn{sub 0.88} and a=474.43(9), b=760.8(2), c=799.0(2) pm, R{sub 1}/wR{sub 2}=0.0226/0.0483, 370 F² values for EuAg{sub 1.17}Zn{sub 0.83} with 13 variables per refinement. Silver and zinc are randomly distributed on the Hg position and build up three-dimensional networks. EuAgZn shows ferromagnetic ordering at 29(1) K.

Spin reorientation in multiferroic spinel Co{sub 0.5}Fe{sub 0.5}Cr{sub 2}O{sub 4} with Mössbauer spectroscopy

Journal Article Myoung, Bo - Journal of Applied Physics

We studied the magnetic properties of multiferroic spinel Co{sub 0.5}Fe{sub 0.5}Cr{sub 2}O{sub 4}, especially focusing on the spin-ordering, spin-reorientation, and charge re-distribution effects. From the Rietveld refinement analysis, the crystal structure was identified to be a normal cubic spinel of Fd-3m. Based on the temperature-dependent measurements of the magnetization and magnetic hyperfine field (H{sub hf}), Curie temperature (T{sub C}) of Co{sub 0.5}Fe{sub 0.5}Cr{sub 2}O{sub 4} was determined to be around 86 K where H{sub hf} ≅ 0. From the change of slope in the M-T curve, the conical-spiral magnetic ordering temperature was determined to be 20 K, which coincides with H{sub hf} measurement. Also,more »« less

Magnetic properties of Zn doped Co{sub 2}Y hexaferrite by using high-field Mössbauer spectroscopy

Journal Article Tae Lim, Jung - Journal of Applied Physics

The polycrystalline samples of Ba{sub 2}Co{sub 2−x}Zn{sub x}Fe{sub 12}O{sub 22} (x = 0.5, 1.0, 1.5) were synthesized by using solid-state-reaction method. From the XRD patterns, analyzed by Rietveld refinement, the prepared samples are found to be single-phased with rhombohedral structure (R-3m). The magnetic properties of samples were investigated with vibrating sample magnetometer, and high-field Mössbauer spectrometer. From the zero-field-cooled curves under 100 Oe between 4.2 and 740 K, we observe that the samples show spin transition from helicalmagnetic to ferrimagnetic order. With increasing Zn ion concentration, the spin transition temperature (T{sub s}) and Curie temperature (T{sub C}) decrease linearly. We have obtained Zero-field Mössbauermore »« less
