The Lake Shore CPX-HF probe station enhances the standard probe station capabilities with the addition of a ±1 T horizontal field superconducting magnet. It can do all the C-V, I-V, microwave, and electro-optical probing that a CPX can do,
plus in-plane horizontal field superconducting magnetic measurements. To maximize the field of the horizontal magnet, however, the sample size is 25 mm (1 in). Researchers can use it for testing magneto-transport parameters. The sample can be maintained at elevated temperature during cooldown, reducing the potential for condensation, a critical requirement for measuring organic materials. The CPX-HF is one of Lake Shore’s premium probe stations for combining microwave measurements
with magnetic field.
The CPX-HF is designed to enable true 90° wafer probing on wafers up to 25 mm (1 in) in diameter. The continuous refrigeration station uses liquid helium and can be operated with liquid nitrogen; however, the superconducting magnet requires liquid helium to operate. The CPX-HF operates over a temperature range of 4.2 K to 400 K with the option to extend the base temperature to 2 K.
