Sentences with word «magnetisation»

For physicists, loss of magnetisation in permanent magnets can be a real concern.

Further advances in understanding the acquisition of magnetisation in archeo - and paleomagnetic data, continuing development of improved laboratory procedures and further investigations of suitability and appropriate scaling of sedimentary relative intensity records will help to reduce uncertainties in the data, and consequently also in the models.

A spin wave is caused by a perturbation of the local magnetisation direction in a magnetic material.

The authors thus extracted the Néel temperature, the zero - temperature staggered magnetisation in the system and the spinwave velocity.

This causes a local magnetisation direction, generating a spin wave in the YIG.

Using variable temperature magnetisation studies the researchers were able to gain key information about the some of the lowest - lying electronic states of the molecules.

The current methods of applying MRAM revolve round the technology which uses an «in - plane», or horizontal, current - induced magnetisation.

Specifically, the law suggests that the Néel temperature can be related to the staggered magnetisation density near a quantum critical point (QCP).

Though Jiles believes that magnetic inspection will be the best way to detect fatigue in steel, he cautions that Erber's method might be sensitive to slight changes in the part's initial magnetisation or other environmental factors.

This heats the film and makes a dot with changed magnetisation.

As a result, spontaneous magnetisation no longer takes place.

The capital city situated at the heart of India serves as the best tourist magnetisation spot.

Firstly, results come from material carrying a thermoremanent magnetisation that has been obtained by cooling through the Curie temperature of the included magnetic minerals.

They have developed methods to counter the spontaneous loss of magnetisation, based on their understanding of the underlying physical phenomenon.

A recently discovered theory shows that the ordering temperature depends on two factors - namely the spin - wave velocity and the staggered magnetisation.

Ferroelectric materials smaller than 10 nm can switch their magnetisation direction using room temperature thermal energy, thus making them useless for memory storage.

The sense of rotation of the magnetisation in the vortex wall — its chirality — can be clockwise or anticlockwise.

A magnetic domain wall forms in a magnetic wire and separates regions where the magnetisation points in opposite directions.

Under certain conditions it consists of a region in which the magnetisation rotates around a central vortex core, which points into or out of the wire.

This enables the heating or cooling of the platinum - YIG interface, depending on the relative orientation of the electron spins in the platinum and the magnetisation in the YIG.

Such a perturbation is caused by an electron with an opposite spin, relative to the magnetisation.

However, if the electron collides on the interface between YIG and platinum, this influences the magnetisation at the YIG surface and the electron spin is transferred.

This is because the potential barriers separating the magnetisation states of different energies are enhanced by the disrupted symmetry.

After magnetising their sample, the researchers observed that the magnetisation rotated in only one of two possible directions, without an obvious reason why one way should be preferred over the other.

Further developments of this research will most likely focus on identifying the discrete magnetisation jumps — elementary events that initiate the reversible magnetisation, leading to a loss in stability.

The magnetisation of the particles in a spin ice can have many different arrangements, all of the same energy.

The controls, particularly combining the double jump with the orbit effect of the magnetisation pull, take a lot of getting used to.

Uncertainties in the ages of these kind of data should in general be no larger than those of the dating methods, as the natural cooling process during which the magnetisation is acquired is comparatively fast.

In that case the sediment age might be older than the age at which the magnetisation of the ambient field gets locked in.

Measurements of the strength of magnetisation can only provide relative variations of past field intensity, and only if the changes can be suitably normalised in order not to reflect lithological or environmental changes.

Secondly, results come from sediment cores that have acquired their magnetisation by embedding magnetic grains aligned with the ambient geomagnetic field.
