چکیده
In this paper, we report the results of magnetic resonance spectroscopy ${\mathrm{EuFe}}_{2}{\mathrm{As}}_{2}$ single crystals. We observe responses, which are attributed to antiferromagnetic resonances Eu sublattice with orthorhombic crystal structure and different orientations twin domains relative external field. confirm validity recently proposed spin Hamiltonian anisotropic Eu-Eu exchange interaction biquadratic Eu-Fe interaction.

La-dilution effects in antiferromagnetic TbRhIn5 single crystals
We report on measurements of temperature-dependent magnetic susceptibility, resonant x-ray magnetic scattering XRMS , and heat capacity on single crystals of Tb1−xLaxRhIn5 for nominal concentrations in the range 0 x 1. TbRhIn5 is an antiferromagnetic AFM compound with TN 46 K, which are the highest TN values along the RRhIn5 series R: rare earth . We explore the suppression of the AFM state as ...
متن کاملTwinned crystals and anomalous phasing.
Merohedral or pseudomerohedral twinning of crystals cannot be identified from inspection of the diffraction patterns. Several methods for the identification of twinning and the estimation of the twin fraction are suitable for macromolecular crystals and all are based on the statistical properties of the measured diffraction intensities. If the crystal twin fraction is estimated and is not too c...
متن کاملMIR phasing using merohedrally twinned crystals.
Merohedral twinning is a crystal-growth disorder that seriously hinders the determination of macromolecular crystal structures by isomorphous replacement. The strategies used in the structures solved so far are discussed. Several methods can be used to determine the extent of twinning, the twin fraction and to detwin the data. Accurate determination of the twin fraction by analysing heavy-atom ...
متن کاملPlasticity and memory effects in the vortex solid phase of twinned YBa2Cu3O7 single crystals
We report on marked memory effects in the vortex system of twinned YBa2Cu3O7 single crystals observed in ac susceptibility measurements. We show that the vortex system can be trapped in different metastable states with variable degree of order arising in response to different system histories. The pressure exerted by the oscillating ac field assists the vortex system in ordering, locally reduci...
متن کاملMacroscopic Symmetry Group Describes Josephson Tunneling in Twinned Crystals
A macroscopic symmetry group describing the superconducting state of an orthorhombically twinned crystal of YBCO is introduced. This macroscopic symmetry group is different for different symmetries of twin boundaries. Josephson tunneling experiments performed on twinned crystals of YBCO determine this macroscopic symmetry group and hence determine the twin boundary symmetry (but do not experime...
