Conductive single-phase SrMoO epitaxial films synthesized in pure Ar ambience via plasma-assisted radio frequency sputtering.

The cubic perovskite SrMoO with a paramagnetic ground state and remarkably low room-temperature resistivity has been considered as a suitable candidate for the new-era oxide-based technology. However, the difficulty of preparing single-phase SrMoO thin films by hydrogen-free sputtering has hindered their practical use, especially due to the formation of thermodynamically favorable SrMoO impurity. In this work, we developed a radio frequency sputtering technology enabling the reduction reaction and achieved conductive epitaxial SrMoO films with pure phase from a SrMoO target in a hydrogen-free, pure argon environment.

Slow spin dynamics of cluster spin-glass spinel Zn(Fe1-xRu)O: role of Jahn-Teller active spin-1/2 Cuions at B-sites.

We report the slow spin dynamics of cluster spin-glass (SG) spinel Zn(Fe1-xRu)Oby means of detaileddc-magnetization andac-susceptibility studies combined with the heat capacity analysis. Two specific compositions ( = 0.5, 0.

Antiferromagnetic short-range order and cluster spin-glass state in diluted spinel ZnTiCoO.

The nature of magnetism in the doubly-diluted spinel ZnTiCoO= (Zn)[TiCo]Ois reported here employing the temperature and magnetic field () dependence of dc susceptibility (), ac susceptibilities (' and″), and heat capacity () measurements. Whereas antiferromagnetic (AFM) Néel temperature= 13.9 K is determined from the peak in the ∂()/∂vsplot, the fit of the relaxation time(determined from the peak in the″ vsdata at different frequencies) to the Power law:=[(-)/]yields the spin glass freezing temperature= 12.
