The transport of electrically charged quasiparticles (based on electrons or ions) plays a pivotal role in modern technology as well as in determining the essential functions of biological organisms. In contrast, the transport of magnetic charges has barely been explored experimentally, mainly because magnetic charges, in contrast to electric ones, are generally considered at best to be convenient macroscopic parameters, rather than well-defined quasiparticles. However, it was recently proposed… 

Creation and measurement of long-lived magnetic monopole currents in spin ice

The recent discovery of ‘magnetricity’ in spin ice raises the question of whether long-lived currents of magnetic ‘monopoles’ can be created and manipulated by applying magnetic fields. Here we show

Electrodynamics in cylindrical symmetry in the magnetic plasma state

Excited states in magnetic structures of the so-called spin-ices and in some artificial magnetic materials present a behaviour as being a magnetic neutral plasma. In this state the electromagnetic

Magnetic monopole dynamics in spin ice.

The diffusive quasi-particle dynamics of real spin ice materials within the 'quantum tunnelling' regime is modelled with Metropolis dynamics, with the particles constrained to move along an underlying network of oriented paths, which are classical analogues of the Dirac strings connecting pairs of Dirac monopoles.

Magnetic Monopole Current in Artificial Square Spin Ice

Recent theoretical and experimental results have revealed the existence of magnetic monopoles, in the form of quasi particles, in both condensed matter known as spin ice, as well as in

Analysis of electromagnetic propagation in the magnetic plasma state in spin-ice systems

Low energy excitation states in magnetic structures of the so-called spin-ices are produced via spin flips among contiguous tetrahedrons of their crystal structure. When there are sufficient free

Magnetic Monopole Noise

Magnetic monopoles are hypothetical elementary particles exhibiting quantized magnetic charge m0 = ±(h/(μ0e)) and quantized magnetic flux Φ0 = ±h/e. In principle, such a magnetic charge can be

Direct observation of magnetic monopole freedom in two-dimensional artificial spin ice

Magnetic monopole unpairing as a function of external magnetic fields is presented as a fingerprint of this emergent quasiparticles freedom in a two-dimensional artificial spin ice system. Such freedom,

Magnetic monopoles in spin ice

This work proposes that magnetic monopoles emerge in a class of exotic magnets known collectively as spin ice: the dipole moment of the underlying electronic degrees of freedom fractionalises into monopoles, which would account for a mysterious phase transition observed experimentally in spin ice in a magnetic field.

Monopole and Dirac string Dynamics in Spin Ice

Magnetic monopoles have eluded experimental detection since their prediction nearly a century ago by Dirac. Recently it has been shown that classical analogues of these enigmatic particles occur as

Every magnet has two poles, north, and south. If we cut a bar magnet in half and wind up with two magnets, each has its own North and South Pole. But physicists have long speculated that unattached

This work reports an artificial geometrically frustrated magnet based on an array of lithographically fabricated single-domain ferromagnetic islands, arranged such that the dipole interactions create a two-dimensional analogue to spin ice, behaviour which is strikingly similar to the low-temperature state of spin ice.
