Features

Overview

Using Hummingbird Scientific’s magnetization holder, scientists can explore how magnetic materials and devices respond dynamically to applied in-plane magnetic fields. Specific applications include studies of the physics of functional magnetic and multiferroic materials such as magnetic alloys, complex oxides, giant/colossal magnetoresistance materials and nanoscale magnetic structures. The magnetization holder is also available in a high-performance version for the dedicated JEOL Lorentz TEM.

Sample Applications:

Directly visualizing magnetic domain switching
Observing microstructure interactions with domain-wall motion
Correlating bulk magnetic measurements with nanoscale processes

Featured Research

Real-space observation of magnetic excitation in quasicrystal lattices

Magnetic reversal mechanism of quasicrystal artificial spin ice were studied with in-situ TEM magnetizing experiments. Using this technique, a team from Argonne National Lab found a new dendritic magnetic reversal mechanism in the quasicrystal spin ice lattitces. “As fabricated” and “Demagnetized” schematics show examples of the groups of magnetic bars whose magnetization reversed at each of the two field values.
