Nanoscale magnetic resonance imaging (NanoMRI) is an
active area
of applied research with potential applications in structural biology
and quantum engineering. The success of this technological vision
hinges on improving the instrument’s sensitivity and functionality.
A particular challenge is the optimization of the magnetic field gradient
required for spatial encoding and of the radio frequency field used
for spin control, in analogy to the components used in clinical MRI.
In this work, we present the fabrication and characterization of a
magnet-in-microstrip device that yields a compact form factor for
both elements. We find that our design leads to a number of advantages,
among them a 4-fold increase of the magnetic field gradient compared
to those achieved with traditional fabrication methods. Our results
can be useful for boosting the efficiency of a variety of different
experimental arrangements and detection principles in the field of
NanoMRI.
