Introduction

Zhang and colleagues applied a magnetic field along single- and few-layer graphene devices and followed the resistance near the Dirac point at low temperatures. They varied the field, temperature and chemical potential to probe how the devices responded.

A closer reading

Field orientation changes the experiment. A perpendicular field quantizes orbital motion in the sheet. Rotating the field into the plane provides a different way to probe resistance near charge neutrality. The abstract specifies what the team measured but does not report a numerical field dependence.
