Electron Spin Resonance
Measurement principleUnder the combined action of high-frequency microwaves and magnetic fields, the sample resonates and absorbs high-frequency microwaves near a certain magnetic field. High-frequency microwaves pass through the sample through a waveguide, and the detector monitors the change of microwave power in real time. The signal is filtered by the preamplifier and recorded by the data a...

Electric Polarization
Measurement principleThe electric polarization in pulsed high field is probed by pyroelectric current technique. In detail, gold electrodes (or silver pastes) are deposited on parallel surfaces of the sample and an electric field E is vertically applied to the golden surface to fully polarize the ferroelectric domains induced by a magnetic field. As the ferroelectric polarization P is generated...

Magnetostriction
Measurement principle The magnetostriction experimental station is a platform that uses magnetostrictive measurement technology to study how the dimensions of samples change with the magnetic field under strong magnetic fields. It employs the Fiber Bragg Gratings method, that the experimental sample is fixed at the bottom end of the measuring probe and is closely bonded with the Bragg grating...

Magnetocaloric
Measurement principle The magnetocaloric effect (MCE) is defined as the temperature change of a magnetic material under adiabatic conditions through the application or removal of a magnetic field. The temperature change of sample is directly detected by a RuO2 thin film thermometer grown on the sample surface by radio-frequency sputtering. The measurement system can be used to investigate the...

Thermal pulse specific heat
Measurement principleThermal pulse specific heat measurement is based on flat-top pulsed magnetic field technology.We use high efficiency heating source and heat conduction material, high sensitivity low temperature thermometer, and small specific heat measurement chip to achieve pulse field specific heat measurement. First, the sample is cooled to the lowest temperature to be measured. Then a ...
