In this research, 30-nm magnetic gold particles were used because they are much more stable than 50-nm magnetic gold particles.
Two independent statistical and modeling approaches were applied, and both of them led us to the conclusions that at larger tilt angles, substorms set off at lower energy input and, conversely, more symmetric current sheets at smaller tilt angles are more effective in storing the magnetic energy and more stable against substorm initiating instabilities.
Magnetic traps have proved more stable; they can hold their quarry for minutes at a time, while atoms typically escape from laser traps after a few seconds.
In addition, magnetic dipoles are normally more stable than electric dipoles and do not require significant energy from outside to maintain their state.
Containing no moving parts, this storage device should prove to be more stable and energy efficient than the traditional on-board magnetic tape data recorder.
The resulting sandwich, in which the ruthenium layer is just three atoms thick, is sufficient to create an effect known as antiferromagnetic coupling, or AFC, in which a stronger and more stable electronic field is created than with conventional single-layer magnetic materials.
The magnetic softness permits using thicker elements that are more stable against temperature fluctations while having low switching fields.
Similarly, since the ferromagnetic double exchange interaction weakens and the charge ordered clusters become more stable with increasing the Pr-doping concentration, as a result, much higher magnetic field (H) is required to destroy the charge ordering [38].
Given the importance of a stable magnetic field to our electricity-dependent, communications-obsessed culture, these questions are of more than academic interest.
