Magnetometry Measurements of Nanomagnetic Materials

Dodrill B.C., Lake Shore Cryotronics, US

Magnetometers are used to characterize magnetic material properties. Magnetometry techniques can be broadly classified into two categories: inductive and force-based. The two most commonly used inductive techniques are vibrating sample (VSM) and superconducting quantum interference [...]

First-Order-Reversal-Curve (Forc) Studies of Nanomagnetic Materials

Dodrill B., Lake Shore Cryotronics, US

The magnetic characterization of nanoscale materials is usually made by measuring a hysteresis loop. However it is not possible to obtain information of interactions or coercivity distributions from the hysteresis loop alone. Studies of magnetic [...]

High-Temperature First-Order-Reversal-Curve (FORC) Study of Magnetic Nanoparticle Materials

Dodrill B., Ohodnicki P., Lake Shore Cryotronics, US

First-order-reversal-curves (FORC) are an elegant tool for characterizing the magnetic properties of materials. The technique has been extensively used to investigate the magnetic properties of natural samples because it can distinguish between different domain states [...]

First-Order-Reversal-Curve Analysis of Nano-composite Permanent Magnets

Dodrill B.C., Lake Shore Cryotronics, US

Rare-earth and ferrite permanent magnet materials are indispensable elements in many electronic devices such as electrical motors, hybrid vehicles, portable communications devices, speakers, sensors, etc. Owing to the decreased availability of, and increasing cost of [...]

First-Order-Reversal-Curve Analysis of Nanoscale Magnetic Materials

Dodrill B.C., Spinu L., Lake Shore Cryotronics, US

Magnetic nanowires, nanodots and nanoparticles are an important class of nanostructured magnetic materials. These structures are ideal candidates for important technological applications in spintronics, high density recording media, microwave electronics, permanent magnets, and for medical [...]

Variable temperature measurements in cryogenic probe stations; forces on the probes

Lindemuth J., Lake Shore Cryotronics, US

Electrical property measurements of nanoscale materials are important for characterization and understanding of materials and devices. Equally important is to measure these properties at various temperatures. We present results using a new probe design that [...]
