Earth quakes are compared with recovery phenomena in crystals and parallels are drawn between the sciences of the seismology in the earth and the acoustic emission in crystals. In a quantitative part the method of the modified Green functions is described which allows us to write complex results ...
μ = 3/24I11/2 fluorescence at ≈2.0 K in the LaCl3 crystal, which are produced by microwave magnetic resonances of the lowest Kramers doublets of Nd3+ in 4I9/2, 4I13/2, and 4I15/2 states and of Er3+ in the 4I15/2 state and U3+ in the 4I9/2 state in the same crystal...
At least six separate rare earth and uranium-bearing daughter crystals occur in fluid inclusions hosted by andraditic garnet from the Mary Kathleen REE-U ore skarn, Queensland, Australia. The daughter minerals are particularly high in La, Nd and Ce which reflects the relatively high concentration...
Choose the crystal that you want to work with and place it in a glass. Fill the glass with drinking water and wait for at least 30 minutes. Remove the crystal and drink in the healing energy. This method is effective for mental and emotional healing, but allowing the crystal’s energy t...
We theoretically investigate a new stabilization mechanism of a skyrmion crystal (SkX) in centrosymmetric itinerant magnets with magnetic anisotropy. By considering a trigonal crystal system without the horizontal mirror plane, we derive an effective spin model with an anisotropic Ruderman–Kittel–Kasuya...
云(cloud)is made of water drops or ice crystals (晶体)漂浮 in the air. There are many kinds of clouds. Clouds are very important to Earth's weather. The sky can be full of water. But most of the time you can't see the water. The drops of water are too small to see. They hav...
Phase transformations in the system MgSiO3 Mg3Al2Si3O12 have been studied at pressures between 22 and 28 GPa, at 1500°C, using a multi-anvil apparatus. M... T Irifune,T Koizumi,JI Ando - 《Physics of the Earth & Planetary Interiors》 被引量: 264发表: 1996年 Experimental determination...
Transmission electron microscopy was used to investigate the cluster formation of trivalent rare earth (RE) ions in wide band gap dielectric crystal hosts with atomic resolution. Various defects and areas with variation in chemical composition with dimensions of 5nm were observed. This finding sets th...
Earthinsync- Terra harmonia - The earth in harmony creates earthly delights for rockhounds, artists, lapidary artists and collectors of crystals, minerals, cabs, slabs, spheres, agates, jaspers, and fossils. Plus mineral kits/specimen kits for educators
A range of experimental techniques was applied including X-ray diffraction, electron microscopy, magnetic susceptibility, magnetization, heat capacity and Mössbauer spectroscopy in the study. We found that Eu has solely a 2+ valence state and its magnetic moments below TN = 19.2 K form a...
