The stability of the pyrochlore structure and the magnetic rare-earth atom (Dy, Ho, etc.) plays a very important role in determining the low-temperature magnetic spin ice ground state of these systems. In this light, we have studied the structural and magnetic phase diagram of Dy_{2-\texti...
Earth's Tilt As the Earth orbits around the sun, it is also spinning on its own axis. The axis is an imaginary line around which an object rotates. The axis of Earth is not perpendicular to its orbital plane but is actually tilted slightly. Earth's tilt is also known as the obliquity...
oftriaxial tests[13]. It is evident that the strength of the rock increases with confining pressure. Such experiments indicate that rocks exhibiting very littleplastic deformationnear the surface of the Earth may be more plastic under high confining pressure. Thus, under a confining pressure of ...
Greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vap
The structural and magnetic properties of the ThCr2Si2-type solid solution LaMn2(Ge1−xSix)2 (x = 0.0 to 1.0) have been investigated employing a combination of X-ray diffraction, magnetization and neutron diffraction measurements, which allowed establishing a magnetic composition-temperature ...

The structure of a stainless steel at room temperature depends to a large extent on its composition. Figure 13.9 shows the Schaeffler diagram, a map showing the fields of dominance of the phases as a function of composition. The labelings A, F, and M stand for austenite, ferrite, and mart...
Uniform quasi-one-dimensional integer spin compounds are of interest as a potential realization of the Haldane conjecture of a gapped spin liquid. This phase, however, has to compete with magnetic anisotropy and long-range ordered phases, the implementation of which depends on the ratio of intercha...
Numerous examples of magnetic phase diagrams of specific materials can be found in other articles (see: Magnetic Phase Transitions: Field-induced (Order to Order), Figs. 1–3, Metamagnetism: Itinerant Electrons, Figs. 1 and 6) and in review papers on magnetism in rare-earth intermetallic compo...
