[en] We present a detailed magnetic study of the perovskite manganite Pr 0.7 Ca 0.3 MnO 3 at low temperatures including magnetization and ac susceptibility measurements. The data appear to exclude a conventional spin glass phase at low fields, suggesting instead the presence of correlated ferromagnetic clusters embedded in a charge-ordered matrix

and grade. Stratigraphic separation from enrichment of only a meter commonly produces heavy mineral grades that are ambient for the area, about 1%. Down-dip, the enriched layers thin to 0.2 m within about 150 m and contain 4 to 10% heavy minerals. The low-grade margins contain significant proportions of the less-dense minerals garnet

Perovskites of the general formula ABX 3 may be regarded as derived from the ReO 3 structure as shown in Fig. 1.The BX 3 framework in the perovskite is similar to that in ReO 3 structure consisting of corner-shared BX 6 octahedra. The large A cation occupies the body center, 12-coordinate position. In an ideal cubic perovskite structure, where the atoms are just touching one another, the B–X

The Mn2+ ions at the A′(A) site contribute local magnetic moments, whereas the V3.75+ ions at the B site play a role in metallic conduction. The observed magnetic behaviors are consistent with the order−disorder distribution of the Mn2+ ions at the A site, antiferromagnetism in the A-site-ordered double perovskites, and magnetic spin glass

Dec 01, 2020 Broadly, three strategies have been used to identify perovskite-inspired materials (PIMs): (1) searching for chemically-analogous materials, (2) investigating materials with a perovskite crystal structure, and (3) inverse design of materials based on defect tolerance [15–18]. This effort spans across multiple academic disciplines

Reviewed in the United States on September 12, 2018. Verified Purchase. I have purchased many (and I mean many) magnetic screen doors all of which I have been disappointed with. I have several large dogs (100 ponds plus) and they are in and out all the time and none of the screen doors lasted even a month without something going wrong with it

Acceptor-doped, redox-active perovskite oxides such as La0.8Sr0.2FeO3 (LSF) are active for ethane oxidation to CO x but show poor selectivity to ethylene. This article reports molten Li2CO3 as an effective “promoter” to modify LSF for chemical looping–oxidative dehydrogenation (CL-ODH) of ethane. Under the working state, the redox catalyst is composed of a molten Li2CO3 layer covering

Nov 10, 2017 The RoHS directive regulates the use of heavy metals in electrical and electronic devices. Other countries, especially the United States and China, usually eventually enact legislation that follows EU regulations, with a delay of several years.
