ChemInform Abstract: Physical Properties of Single-Crystalline Magnetic Intermetallic Compounds

Aluminum-rich intermetallic compounds of the Al3X-type with transmission metals (X = Ti. Zr, Nb, V) of Groups IVb and Vb are of interest in the development of novel high-temperature and lightweight structural materials. This article describes the important physical and mechanical properties of trialuminides with DO22 structure and their L12 variations. Topical coverage includes: crystal structure and selected physical properties, plastic deformation, oxidation behavior, and applications.

Some intermetallic compounds which contain uranium or cerium present heavy fermion characteristics. Take, for example, in the UM 2 Al 3 ( M = Pd , Ni ) family, superconductivity and magnetism coexist and present heavy fermion behavior. This work presents the crystallographic characteristics and physical properties of a new compound of this family; the intermetallic compound UCo 2 Al 3. Our initial crystallographic studies performed in a small single crystal show that the structure is hexagonal and similar to the UNi 2 Al 3 and UPd 2 Al 3 parent compounds. The space group is P6/mmm with a=5.125 Å and c=4.167 Å crystalline parameters. Measurements of resistivity and magnetization performed on the single crystal reveal that the compound is not superconducting when measured at about 1.8 K. The compound is highly anisotropic and features related to Kondo-like behavior are observed. A weak ferromagnetic transition is observed at a temperature of about 20 K.

Single Crystalline

A nanocasting method using SBA-15 as a hard template was adopted to prepare mesoporous nanocrystalline ANbO3 (A = Li, Na, and K) samples. The characteristics of samples werecharacterized by techniques such asXRD, N2-sorption measurement, HRTEM and UVDRS. It was found that thealkality of the alkali metals could have profound impacts on the synthesis andthe physical properties of samples. The Li, Na, and K precursors can reacteasily with the siliceous template, and the reactivity varies with the alkalityof the alkali metal. The synthesis of KNbO3 is unsuccessful because of the high alkality ofK. The templated LiNbO3 andNaNbO3 consist of single crystalline nanoparticles that generate interparticle mesoporosity. The LiNbO3andNaNbO3 samples showed notably enhanced photocatalytic activitiesfor 2-propanol photodegradation in comparison to the counterparts prepared bythe solid state reaction.
