Influence of the interface in quantum corrections on the low-temperature resistance of La2/3Sr1/3MnO3 trilayer masking thin films

“…[1][2][3][4][5][6][7] The observed phenomenon is similar to the Kondo effect, which was first found in the crystalline noble-metal alloys with low magnetic impurity concentration.

Manganese: Inorganic & Coordination ChemistryBased in part on the article Manganese: Inorganic & Coordination Chemistry by Charles A. McAuliffe, Stephen M. Godfrey, & Michael Watkinson which appeared in theEncyclopedia of Inorganic Chemistry, First Edition.

“…The electronic configuration of manganese(III) is 3d 4 , and therefore, the high-spin configuration in an octahedral field is subject to Jahn -Teller distortion like for Cu II 78 have been studied and this technique has been proposed as a useful tool for the structural investigation of these complexes and also for mixed-valence clusters incorporing manganese (III) 79 (see Section 5).…”

Coordination Chemistry of Lanthanides at “High” pH: Synthesis and Structure of the Pentadecanuclear Complex of Europium(III) with Tyrosine

“…The highly ordered arrangement of the metal centers in these nano-sized clusters is expected to yield useful magnetic properties. [5,7,8] We believe that the novel structural patterns (and any accompanying physical/chemical properties), coupled with the ability to construct a huge variety of lanthanide clusters will undoubtedly enhance our understanding of lanthanide-based molecular magnetic materials.…”

“…Spectacular clusters such as polyoxovanadates, [6] ferric weels, [3b] and manganese clusters [7] have been reported and proven to exhibit rather interesting magnetic properties. [5,7,8] Despite all the progress that has been made in controlling excessive hydrolysis during the formation of metal clusters, a suitable and general class of supporting ligands is yet to be identified for the preparation of lanthanide-based clusters. [5] Lanthanide clusters are expected to exhibit more promising magnetic properties as a consequence of the unique spectroscopic and electronic properties mainly associated with their 4f n electronic configurations.…”

“…Several classes of ligands have been utilized in this capacity, among which carboxylates, [3] polyketonates, [4] and alkoxides [5] are prominent. Spectacular clusters such as polyoxovanadates, [6] ferric weels, [3b] and manganese clusters [7] …”
