Users are advised to place power supplies and controllers in separate cabinets to avoid damage and ensure proper operation. Correct connections are crucial to prevent irreversible damage to the electromagnet.
Manually adjust the lifting and magnification knobs to ensure the microscope is at an appropriate height and magnification for clear image display.
The sample stage is manually driven. Adjust the X, Y, Z, T, and θ axes to position the sample correctly, avoiding collisions with the electromagnet.
Place the sample on the ceramic table and adjust the displacement tables to align the sample with the microscope's field of view.
Position the sample image centrally on the microscope display, adjust magnification, and insert probes sequentially to contact the device under test.
Sequentially turn on the water chiller, electromagnet power supply, source meter, voltmeter, control computer, and testing program.
Steps include placing the sample, adjusting the microscope and displacement table, positioning the probe, and starting the test.
Close the testing program, turn off the control computer, source meter, voltmeter, electromagnet power supply, and water chiller.
Align the microscope lens with the magnetic field center. If misalignment occurs, recalibrate using the specified steps.
Ensure all instruments are on before software use. The main interface includes a menu bar, display interface, and monitoring interface. Set communication ports and perform tests like resistance and magnetoresistance measurements.
Set parameters such as current and voltage limits. The data display shows the V-I relationship.
Configure parameters for scanning sequences and sampling points. The data display includes R-H and V-H diagrams.
Set parameters for pulse width and delay. The test minimizes thermal effects and errors. Data display includes R-I and V-H diagrams.
Set parameters for sensitivity and harmonic frequency. The data display includes test and fitting pages.
The document outlines the equipment required for measuring the second harmonic of variable fields and currents, including the Keithley 6221 current source, Stanford SR830 lock-in amplifiers, magnet power supplies, and a Gaussian meter. It specifies the need for accurate hardware wiring and communication checks before operation.
- Second Harmonic Measurement: Steps include checking hardware, setting file paths, selecting measurement interfaces, and starting measurements to obtain relationship curves and fitting parameters.
- Resistance (R-I) Measurement: Involves setting current parameters, file paths, and starting measurements to obtain curve graphs.
- Magnetoresistance (R-H) Measurement: Similar to R-I measurement but includes magnetic field sequence settings.
- Pulse Resistance Measurement: Requires switching the current source to pulse mode and setting pulse parameters.
The document details settings for controlling magnetic fields, including parameter settings for in-plane and vertical magnetic fields, error tolerance, stabilization time, and demagnetization procedures.
The configuration file for the 2D magnetic field probe station software is automatically loaded and saved, containing instrument addresses and data preservation paths.
Includes guidelines for operating temperatures, coolant usage, power supply management, and equipment handling to prevent damage and ensure safety.
The product has a one-year warranty covering malfunctions under normal use. Exclusions include improper use, self-repair, and external damage. The company disclaims liability for special, incidental, or indirect damages.
