Product Model:

PS1DP-Cryo

Product Overview:

● The PS1DP-Cryo Superconducting Magnet Closed Cycle Cryogenic Probe Station, which is fabricated by adding ±3 T of superconducting magnets to a 4 K closed cycle cryogenic probe station, provides a low-temperature environment with a high magnetic field for samples, and can hold 2-inch samples. In addition to all standard I-V, C-V, microwave, optical and electrical measurements, the probe station provides a high magnetic field environment for the measurements of electric transport of Two-dimensional materials, Spintronic device transport, Superconducting materials, Semiconductor materials, or Device Hall Effect.

● The PS1DP-Cryo Probe Station comes with complete control and testing software to provide users with automated, systematic test solutions. The software allows users to monitor and control the temperature and magnetic field of the probe station in real time. Coupled with the DC and microwave test sequences such as Magnetoresistance, Second harmonic, Spin-torque ferromagnetic resonance (ST-FMR), and Spin pumping contained in the software, the probe station is an efficient solution to the characterization of electric transport at low temperatures and in high magnetic fields.

The high-degree system integration enables one-button temperature and magnetic field control and electrical testing through software operation.

● Cooling with a 4 K GM refrigerator, without refrigerant required in the cooling process

● Temperature range of the sample stage: 4K～420K

● Temperature stability is greater than ±20 mK over the entire temperature range

● Carry vertical superconducting magnets with a maximum magnetic field of ±3 T

● Multiple heat sinks are designed for the probe arms and probes to minimize the sample temperature rise caused by probe feeding

● The quick sample change option reduces the time for a single sample change by 2 hours

● The advanced intelligent optical system enables clearer sample observation and supports various functions such as recording, shooting and distance measurement.

● The special vibration damping design effectively reduces the vibration of the sample stage, ensuring the vibration <1 μm (p-p) over the full temperature range, which meets the needs of most optical devices for continuous operation.

Magnetoresistance Measurements

The product can be used to measure magnetoresistance, anomalous Hall magnetoresistance, tunneling magnetoresistance and giant magnetoresistance effects. The mode of applying the magnetic field can be set arbitrarily, making it easy to meet various measurement requirements.

Hall Effect Measurements

The resistivity and Hall voltage of a semiconductor material are measured using a current source and nanovoltmeter, and the carrier concentration, mobility, resistivity, Hall coefficient and other parameters of the semiconductor material are calculated. Hall measurement is a common means of understanding and studying the electrical properties of semiconductor devices and materials.
