“…The i-R-Cd quasicrystals used in this study were grown from a binary melt using the solution growth method described previously, 23,30,33 and subsequently annealed at 200 • for three days. Small single grains, approximately 100 µm × 100 µm × 100 µm in size, were extracted from the growths for R = Gd, Dy, and Tm in order to sample the structural trends across the series of heavy rare earths.…”

Pressure tuning of competing magnetic interactions in intermetallic CeFe2

We use high-pressure magnetic x-ray diffraction and numerical simulation to determine the lowtemperature magnetic phase diagram of stoichiometric CeFe2. Near 1.5 GPa we find a transition from ferromagnetism to antiferromagnetism, accompanied by a rhombohedral distortion of the cubic Laves crystal lattice. By comparing pressure and chemical substitution we find that the phase transition is controlled by a shift of magnetic frustration from the Ce-Ce to the Fe-Fe sub-lattice. Notably the dominant Ce-Fe magnetic interaction, which sets the temperature scale for the onset of long range order, remains satisfied throughout the phase diagram but does not determine the magnetic ground state. Our results illustrate the complexity of a system with multiple, competing magnetic energy scales and lead to a general model for magnetism in cubic Laves phase intermetallic compounds.

Field dependence of the superconducting basal plane anisotropy of TmNi2B2C

et al. 2012

View full text Add to dashboard Cite

The superconductor TmNi 2 B 2 C possesses a significant four-fold basal plane anisotropy, leading to a square Vortex Lattice (VL) at intermediate fields. However, unlike other members of the borocarbide superconductors, the anisotropy in TmNi 2 B 2 C appears to decrease with increasing field, evident by a reentrance of the square VL phase. We have used Small Angle Neutron Scattering measurements of the VL to study the field dependence of the anisotropy. Our results provide a direct, quantitative measurement of the decreasing anisotropy. We attribute this reduction of the basal plane anisotropy to the strong Pauli paramagnetic effects observed in TmNi 2 B 2 C and the resulting expansion of vortex cores near H c2 .
