They found that at temperatures just above and below 70 degrees Kelvin, they could readily magnetize the SmAl2 alloy
using an external magnetic field.
To overcome these issues, Steven J. Jonas, Paul S. Weiss, Xiaobin Xu and colleagues sought to create biocompatible nanospears that can be configured to transport DNA into cells precisely
using an external magnetic field without either damaging the cells or having to use chemical propellants.
«These larger crystals are easier to control
using external magnetic fields, and they will not aggregate when those fields are removed, which will make them much more useful in practical applications, including drug delivery.»

Now scientists have found through close examination that
external magnetic fields can be
used to coordinate and accelerate some of these flips — perhaps clearing the way to new and improved read / write heads and greater storage density.
«Due to their low energy, it is significantly easier to influence them
using parameters such as pressure or an
external magnetic field.»
Using a computer, they simulated how the DMI and
external magnetic fields of varying strengths affected the modes and properties of the particles.
The capsule is
used with a fixed
external magnet and its position is tracked precisely by measuring the strength and direction of the
magnetic field it experiences.
