The Lake Shore Model EMPX-HF probe station enhances the standard probe station capabilities with the addition of a ±0.55 T horizontal field electromagnet. All standard CV, IV, microwave, and electro-optical probing, plus in-plane horizontal field electromagnetic measurements can be performed on this versatile station. Researchers can use it for testing magneto-transport parameters. The EMPX‑HF is Lake Shore’s premier probe station for vector-dependent magneto-transport measurements.

To maximize magnetic field at the sample, the EMPX-HF has its probes configured at 30° angles for probing wafers up to 25 mm (1 in) in diameter. A 360° sample stage rotation option allows measurement of angular-dependent and anisotropic magneto-transport properties. The EMPX-HF operates over a temperature range of 4.5 K to 400 K, with the option to extend the base temperature to 3.2 K. The continuous refrigeration EMPX-HF uses can be operated with liquid helium or liquid nitrogen for cooling.
