We present a dual scanning tunneling microscope (DSTM) system operating between and room temperature, in a split-coil superconducting magnetic field up to and in ultrahigh vacuum. The DSTM consists of two compact STMs, each having , , and coarse positioning piezoelectric steppers with embedded capacitive positioning sensor for navigation. Each STM can be operated independently and can achieve atomic resolution. The DSTM and the sample is configured in a way that allows the magnetic field orientation to be varied continuously from normal to parallel to the sample surface. Together with the sample, the DSTM can form a nanometer scale three terminal setup for transport measurement.
