This study of the RAgSb 2 series of compounds arose as part of an investigation of rare earth intermetallic compounds containing antimony with the rare earth in a position with tetragonal point symmetry. Materials with the rare earth in a position with tetragonal point symmetry frequently manifest strong anisotropies and rich complexity in the magnetic properties, and yet are simple . The first family of rare-earth-based single chain magnets is presented. Compounds of general formula [M(hfac)3(NITPhOPh)], where M = Eu, Gd, Tb, Dy, Ho, Er, or Yb, and PhOPh is the nitronyl−nitroxide radical (2,4‘-benzoxo-4,4,5,5-tetramethylimidazolineoxyloxide), have been structurally characterized and found to be isostructural. The characterization of both static and Cited by:
Magnetic Order in Superconductors. The effects of magnetic impurities and the possibility of magnetic ordering in superconductors has had a rich and interesting history, and we have had a longstanding interest in investigating such systems. In the following example we have rare earth ordering at low T, Ru magnetic ordering at quite high T. Here we report on results obtained by small angle neutron scattering on the FLL in LuNi 2 B 2 C with the applied magnetic field parallel to the crystalline c-axis, measuring the temperature dependence of the hexagonal to square symmetry transition. Models based on respectively the London theory and the Ginzburg-Landau theory predicts two.
Since , layered compounds containing Bi-Ch (Ch: S and Se) layers have been extensively studied in the field of superconductivity. The most-studied system is BiS2-based superconductors with two-layer-type conducting layers. Recently, superconductivity was observed in La2O2M2S6 (M = metals), which contains four-layer-type conducting layers. The four-layer-type Bi-based .

The results of research on the crystalline-electric-field (CEF) effect in RCu 2, R 2 Fe 14 B and RFe 11 Ti compounds are presented. In the study of the CEF effect in the RCu 2 compounds, attention is paid to the combined analysis of specific heat and thermal expansion.
An attempt has been undertaken to investigate the systematic behavior of CEF interactions by comparing Cited by: 2. A theory is developed for interpreting the effects of the crystalline electric field in non-magnetic metals containing small quantities of magnetic ra Cited by: 2.
Rare-earth (RE) based compounds and alloys are of great interest both for their fundamental physical properties and for applications (e.g. for producing new-generation solid-state laser and high-performance magnetic materials). In order to tailor the.

MUller and V. Narozhnyi. A comparison is made with the magnetic properties of rare‐earth‐iron and ‐cobalt compounds. Magnetic data are reported for La 3 Co, Y 3 Co, and YCo 2 which are paramagnetic. Curie. This maturation is also seen in the growing realization of the effects of CEF on transport, thermodynamic properties, and superconductivity and its co-existence with magnetic order.

In contrast, Pr2Fe14B remains axial down to K. We show that this behavior in the Pr and Nd compounds results from an interplay of crystalline electric field (CEF) effects and the R‐Fe exchange interaction.

A magnet is a material or object that produces a magnetic magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.Recent studies of the magnetic properties of rare earth (RE) atoms dissolved in metals and particularly in Pd are reviewed.
