Magnetic Susceptibility and Permeability

Magnetic Susceptibility and Permeability

In linear magnetic materials, like paramagnets and diamagnets, magnetization is proportional to the magnetic field intensity. The constant of proportionality, a dimensionless number, is called magnetic susceptibility. The value of the susceptibility depends on the type of material.
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...

Background:

Experiments in the milliKelvin regime demand materials with specific thermal and electrical properties.
Balancing high thermal conductivity for heat sinking and low electrical conductivity for reduced eddy-current heating is challenging.

Purpose of the Study:

To design and implement a coil mounting system for magnetic susceptibility measurements in the milliKelvin range.
To overcome the limitations of traditional materials in low-temperature, high-frequency experiments.

Main Methods:

Utilized a nonmetallic construction for the coil mounting system.
Employed a sapphire skeleton and a machined carbon-fiber body.
Integrated the system into an apparatus for milliKelvin experiments.

Main Results:

The nonmetallic coil mount successfully minimized eddy-current heating.
Enabled the use of large AC magnetic field amplitudes at kHz frequencies and above.
Facilitated unprecedented studies of nonlinear magnetic dynamics.

Conclusions:

The novel coil mounting system effectively resolves the material selection dilemma for milliKelvin magnetic susceptibility measurements.
This advancement opens new avenues for exploring complex magnetic phenomena at high frequencies.
