Scanning SQUID susceptometers with sub-micron spatial resolution.
Scanning SQUID susceptometers that achieve sub-micron spatial resolution while retaining a white noise floor flux sensitivity of ≈2μΦ0/Hz1/2 and have integrated modulation coils for flux feedback, integrated field coils for susceptibility measurements, and batch processing are described. Expand
Determining the vibrations between sensor and sample in SQUID microscopy
Vibrations can cause noise in scanning probe microscopies. Relative vibrations between the scanning sensor and the sample are important but can be more difficult to determine than absolute vibrationsExpand
Scanning SQUID sampler with 40-ps time resolution.
This work presents the design, fabrication, and characterization of a novel scanning SQUID sampler with a 40-ps time resolution and linearized response to periodically triggered signals, useful for imaging dynamics in magnetic and superconducting materials and devices. Expand
The response of small SQUID pickup loops to magnetic fields
In the past, magnetic images acquired using scanning superconducting quantum interference device (SQUID) microscopy have been interpreted using simple models for the sensor point spread function.Expand
Magnetic coupling at rare earth ferromagnet/transition metal ferromagnet interfaces: A comprehensive study of Gd/Ni
An exhaustive study of nickel/gadolinium as a model system for understanding RE/TM multilayers using the element-specific measurement technique x-ray magnetic circular dichroism is performed, and the full magnetic state diagrams are determined as a function of temperature and magnetic layer thickness.

Electric coupling in scanning SQUID measurements
Scanning SQUID is a local magnetometer which can image flux through its pickup loop due to DC magnetic fields ($\Phi$). Scanning SQUID can also measure a sample's magnetic response to an appliedExpand

Spatially modulated magnetic structure of EuS due to the tetragonal domain structure of SrTiO
The combination of ferromagnets with topological superconductors or insulators allows for new phases of matter that support excitations such as chiral edge modes and Majorana fermions. EuS, aExpand
Research data supporting "Magnetic coupling at rare earth ferromagnet/transition metal ferromagnet interfaces: A comprehensive study of Gd/Ni"
X-ray magnetic circular dichroism (XMCD) measurements of Ni/Gd/Ni thin-film multilayers grown by D.C. magnetron sputtering. Measurements were performed between the temperature range of 6 K and roomExpand
