Description

<jats:p>A scanning force microscope was implemented operating at temperatures below 4.2 K and in magnetic fields up to 8 T. Piezoelectric quartz tuning forks were employed for nonoptical tip–sample distance control in the dynamic operation mode. Fast response was achieved by using a phase-locked loop for driving the mechanical oscillator. Possible applications of this setup for various scanning probe techniques are discussed.</jats:p>
