Senjedak II & III prospect areas are part of eastern anomalies of the Sangan mine, which is located in northwest of Khaf. The geology of the area consists of Pre-Cambrian schistes, Jurassic and Lower Cretaceous sedimentary rocks, and tuff and biotite monzonite porphyry intrusion with Eocene age. Skarn types in the Senjedak III include pyroxene–garnet skarn, garnet–pyroxene skarn, garnet skarn, ...
The problem of deducing the values of the exchange integrals in yttrium and gadolinium iron garnet from measurements of the magnetization and the magnetic contribution to the specific heat at low temperatures is considered. For these garnets the spin-wave normal modes can be found by solving the semiclassical equations of motion which give rise to a set of n simultaneous linear equations, where...
The title compound, penta-iron tripraseodymium dodeca-oxide (PrIG), has an iron garnet structure. There are two Fe site symmetries. One of the Fe atoms is coordinated by six O atoms, forming a slightly distorted octa-hedron, and has site symmetry. The other Fe atom is coordinated by four O atoms, forming a slightly distorted tetra-hedron, and has site symmetry. FeO(6) octa-hedra and FeO(4) tetr...
In north of Anarak area, in the upper Proterozoic ophiolite, exist Massive and Vein type Rodingites. Vein type rodingites have formed in two phases. Massive or Static rodingites have formed during oceanic crust spreading and ophiolite formation, and Vein type or Dynamic rodingites have formed during Anarak ophiolite emplacement and tectonic activities. Abundance order of minerals in massive rod...
The Anjir Khajeh area is located in the southern part of Sanandaj-Sirjan metamorphic belt in northwest of Golgohar iron mine. The rock units of the region include metabasites, metasediments, igneous and sedimentary rocks. Metasedimentary rocks containing mica-schist, garnet schist, and garnet staurolite schist, having metamorphosed into greenschist facies and amphibolite facies. Garnet mineral ...
Introduction: Magneto-optics (MO) technology is believed to be far more advanced in the former Soviet Union when compared to the US. This is evidenced by the existence of factories geared for the production of Yttrium Iron Garnet (YIG) wafers. The potential advantages to MO Crystal Technology over other magnetic sensing technologies are (1) light weight and compact construction, (2) low cost, a...
Combinatorial pulsed laser deposition of doped yttrium iron garnet films on yttrium aluminium garnet
We have studied the dynamics of iron-garnet films using a pump-probe technique and were able to demonstrate that the response time of such a film is sufficiently short to investigate sub-nanosecond phenomena. Furthermore, we studied the penetration velocity of the dendritic instability in thin YBCO films. We found two regimes: An early stage with a penetration velocity of up to 17Okmls and a di...
