Title First order magnetic transition and magnetoelastic effects in Sm2IrIn8 Type Journal Article
Year (up) 2008 Publication Physica B Abbreviated Journal
Volume 403 Issue 5-9 Pages 1365-1367
Keywords First order magnetic phase transition; Magnetotrictive effects; CEF effects
Abstract We report measurements of temperature dependent heat capacity, thermal expansion and high resolution X-ray diffraction (XRD) taken on single crystals of Sm2IrIn8 intermetallic compound. This compound belongs to the RmMnIn3m+2n family (R=rare earth, m=1, 2, n=0, 1 and M=Rh, Ir and Co) which includes a number of heavy fermion superconductors for R=Ce. Particularly, Sm2IrIn8 is the only member of this family to present a first order magnetic phase transition (FOMT). Both thermal expansion and heat capacity data show very pronounced sharps peaks at View the MathML source consistent with an FOMT. The linear thermal-expansion coefficient is anisotropic and both c-axis and basal ab plane coefficients change discontinuously at 14.2 K. This change is negative for both direction in contrast to what was found for other members of family such as Ce2RhIn8 and CeRhIn5. The zero-field high resolution XRD data at 14.2 K shows no evidence for a tetragonal-to-orthorhombic structural phase transition. We discuss our results considering tetragonal crystalline field effects (CEF), quadupolar interactions, antiferromagnetic domains and magnetoelastic effects.

Title High magnetic field lattice length changes in URu2Si2 Type Journal Article
Year (up) 2012 Publication Physical Review Letters Abbreviated Journal
Volume 109 Issue Pages 246405
Keywords
Abstract We report high-magnetic-field (up to 45 T) ^ c-axis thermal-expansion and magnetostriction experiments on URu2Si2 single crystals. The sample length change  associated with the transition to the ‘‘hidden order’’ phase becomes increasingly discontinuous as the magnetic field is raised above 25 T. The

reentrant ordered phase III is clearly observed in both the thermal expansion and magnetostriction above 36 T, in good agreement with previous results. The sample length is also discontinuous at the boundaries of this phase, mainly at the upper boundary. A change in the sign of the coefficient of thermal expansion is observed at the metamagnetic transition (BM  38 T), which is likely related to the existence of a quantum critical end point.
