Spin ice - Wikipedia.

For artificial spin ice, this analysis shows that nearest-neighbour correlations drive longer-range ones. From thermodynamic origins, the concept of entropy has expanded to a range of statistical measures of uncertainty, which may still be thermodynamically significant.

Motivated by the puzzling experiments on two pyrochlore systems Pr2Ir2O7 and Yb2Ti2O7, we study the proximate magnetic orders and the related quantum phase transition out of quantum spin ice (QSI). The application of a magnetic field along the [111] direction in the spin ice compounds leads to two magnetization plateaux, in the first of which the ground-state entropy is reduced but still remains extensive. We observe that under reasonable assumptions, the remaining degrees of freedom in the low field plateau live on decoupled kagome planes, and can be mapped to hard core dimers on a. In magnonic crystals, spin waves are functionalized for logic applications by means of band structure engineering. While it has been established that artificial spin ices can possess rich mode spectra, the applicability of spin ices to create magnonic crystals hinges upon their reconfigurability.

Theory of the [111] magnetization plateau in spin ice.

Spin ice (1) is a remarkably simple system in some ways; as a first approximation it is simply a classical Ising antiferromagnet. However, this simplicity is deceptive.... ground states via independent application of the tetrahedral constraints. This is equivalent to a ground state entropy per spin S p=k BN s ¼ð1=2Þlogð3=2Þ, in fine.

PDF Spin Ice, Fractionalization, and Topological Order.

As a measure of disorder, entropy is a central concept of statistical mechanics. In practice, however, it is typically determined thermodynamically, that is, by measuring heat. However, in arrays of interacting submicrometre-sized magnetic islands—known as artificial spin ice—entropy can be determined directly by ‘counting’ the microstate of the system.

Hidden phases born of a quantum spin liquid: Application to pyrochlore spin ice. Quantum spin liquids (QSL) have generated considerable excitement as phases of matter with emergent gauge structures and fractionalized excitations. In this context, phase transitions out of QSLs have been widely discussed as Higgs transitions from deconfined to.

This paper analyses sustainability and efficiency of organizations principally involved in exploitation of tule Thypha spp on Zapotlán's Lake taking into consideration their socioeconomic and environmental impact on the municipalities of Gómez Farías. Artificial spin ice (ASI) has become a medium of interest for both its behaviour as a meta-material (Stepney, 2008), and its computational potential (Jensen et al., 2018). ASI is a ferromagnetic.

We confirm that it works for spin ice, Dy2Ti2O7, which recommends its application to other systems. The analysis described here also gives an insight into the dependence of entropy on magnetic moment, which plays an important role in the theory of magnetic monopoles in spin ice.

Skating on spin ice: On the application of Lorentz microscopy and. Our artificial spin ice [15] systems are arrays of litho- graphically defined single-domain ferromagnetic islands (25 nm thick and 220 nm 80 nm in area) on the links of square and honeycomb lattices (Fig. 1). A spin ice is a magnetic substance that does not have a single minimal-energy has magnetic moments (i.e. "spin") as elementary degrees of freedom which are subject to frustrated their nature, these interactions prevent the moments from exhibiting a periodic pattern in their orientation down to a temperature much below the.

From thermodynamic origins, the concept of entropy has expanded to a range of statistical measures of uncertainty, which may still be thermodynamically significant 1, 2. But, labo. Spin ices are materials that consist of regular corner-linked tetrahedra of magnetic ions, each of which has a non-zero magnetic moment, often abridged to "spin", which must satisfy in their low-energy state a "two-in, two-out" rule on each tetrahedron making the crystalline structure (see figure 2).
