electronic and Magnetic Phase Diagram of superconductors smfeaso1 xfx
New Journal of Physics, 2010Co-Authors: Yoichi Kamihara, Takatoshi Nomura, Masahiro Hirano, Jungeun Kim, Kenichi Kato, Masaki Takata, Yasuhiro Kobayashi, Shinji Kitao, Satoshi Higashitaniguchi, Yoshitaka YodaAbstract:A crystallographic and Magnetic Phase Diagram of SmFeAsO1−xFx is determined as a function of x in terms of temperature based on electrical transport and magnetization, synchrotron powder x-ray diffraction, 57Fe Mossbauer spectra (MS), and 149Sm nuclear resonant forward scattering (NRFS) measurements. MS revealed that the Magnetic moments of Fe were aligned antiferroMagnetically at ~144 K (TN(Fe)). The Magnetic moment of Fe (MFe) is estimated to be 0.34 μB/Fe at 4.2 K for undoped SmFeAsO; MFe is quenched in superconducting F-doped SmFeAsO. 149Sm NRFS spectra revealed that the Magnetic moments of Sm start to order antiferroMagnetically at 5.6 K (undoped) and 4.4 K (TN(Sm)) (x=0.069). Results clearly indicate that the antiferroMagnetic (AF) Sm sublattice coexists with the superconducting Phase in SmFeAsO1−xFx below TN(Sm), while the AF Fe sublattice does not coexist with the superconducting Phase.

DILATOMETRIC STUDY OF THE Magnetic Phase-Diagram OF ERBIUM
Journal of Magnetism and Magnetic Materials, 1995Co-Authors: S. Zochowski, K.a. McewenAbstract:Abstract The Magnetic Phase Diagram of erbium has been constructed from the observed anomalies in thermal expansion and longitudinal magnetostriction measurements. Using a capacitance dilatometer, single crystal measurements were made parallel to the crystallographic c -axis in the temperature range 2–100 K and in fields up to 7 T. Features of the Phase Diagram are compared with those of Diagrams deduced from previous neutron scattering studies.

Thermal expansion and magnetostriction of UNi2Si2: The Magnetic Phase Diagram
Journal of Magnetism and Magnetic Materials, 1995Co-Authors: S. Zochowski, S.a. Creeger, Malcolm F. CollinsAbstract:Abstract Thermal expansion and magnetostriction measurements are reported for single-crystal UNi 2 Si 2 . For Magnetic fields up to 15 T applied along the c direction and in the temperature range 2–150 K distinct features and anomalies observed in the combined results are used to construct a Magnetic Phase Diagram. The Diagram extends that deduced from neutron scattering work at low fields.

The Magnetic Phase Diagram of UNi2Si2
Physica B-condensed Matter, 1992Co-Authors: L. Rebelsky, H. Lin, M.w. Mcelfresh, Malcolm F. Collins, J. D. Garrett, W.j.l. Buyers, M. S. TorikachviliAbstract:Abstract Neutron diffraction and magnetization measurements as a function of applied Magnetic field are reported for single crystal UNi 2 Si 2 . The combined results are used to construct a Magnetic Phase Diagram for applied fields along c . The simple body-centered antiferroMagnetic Phase, stable in zero field from 55 K to 103 K, is suppressed completely by fields greater than 3.8 T. There is a reentrant triple point at 102.8 K and 2.1 T.

Magnetic Phase Diagram of UNiGa
Journal of Magnetism and Magnetic Materials, 1995Co-Authors: Vladimír Sechovský, Ladislav Havela, Pavel Svoboda, A.v. Andreev, P. Burlet, K. Prokes, Heinz Nakotte, F.r. De Boer, E.h. Brück, R.a. RobinsonAbstract:Abstract We present a complex Magnetic Phase Diagram of UNiGa with several antiferroMagnetic (AF) Phases below T N = 39.5 K. A relatively low Magnetic field (∼ 1 T) applied along the c -axis induces a transition from the AF Phases to an uncompensated AF and/or a ferroMagnetic (F) Phase. All the Magnetic structures are collinear ( μ U ⊥ c ) and consist of ferroMagnetic basal-plane sheets with various coupling along c .

Magnetic Phase Diagram in NdIn3
Journal of Magnetism and Magnetic Materials, 1995Co-Authors: M. Amara, Rose-marie Galéra, P. Morin, J. Voiron, P. BurletAbstract:Abstract We attempt a quantitative description of a (H-T) Magnetic Phase Diagram of the cubic compound NdIn3. Below TN, this compound presents two spontaneous first-order Phase transitions as well as several field induced transitions. Considering both the dipolar and quadrupolar interactions a self-consistent periodic-field model is proposed. Although the metaMagnetic magnetization processes at low temperatures are not totally reproduced, the calculations account quantitatively for the spontaneous Magnetic Phase succession.
