PMA (Passive Magnetic Anvil) is an accessory device for carrying out pressure-temperature experiments in laboratory that can realize low-pressure and high-temperature measurement. It has been widely used in many fields such as materials science, physics, chemistry, nanotechnology and biology for the purpose of studying the properties of materials under external pressure. It has a unique advantage over conventional techniques of high-precision measurement under pressure and temperature.

PMA\'s applications in the field include but are not limited to: studying the physical and chemical properties of materials under external pressure and temperature; studying the reaction between two different materials and their influence on each other; measuring the elastic modulus and phonon modes of the elastic stiffness of the material; studying the adsorption and desorption of certain molecules on the material surface; and researching the transient thermal phenomena in the material. It can also be applied to other fields such as materials screening and characterization, and characterization of material structure and design.

The working principle of PMA is simple: the sample is placed between two anvils and a pressure is applied. The force applied to the anvils can be varied, and the pressure generated by the anvils is transmitted to the sample through a specially designed sample holder. The sample is then exposed to external pressure and temperature conditions and the measurement of the properties of the material can be obtained by measuring the response of the sample.

PMA has many advantages compared with other techniques. For example, it is more precise than traditional pressure-temperature techniques such as the diamond anvil cell (DAC), as it can provide higher accuracy in data acquisition. Also, it is more efficient with its ability to rapidly adjust the pressure to achieve accurate measurements over a wide range of temperatures. Furthermore, it provides better control over the pressure-temperature environment, and the ability to maintain a stable environment for long times.

PMA is a versatile and efficient tool for measuring material properties and studying changes in material properties under pressure. With its ability to rapidly adjust the pressure and temperature, it is an invaluable tool for research and development in materials science, physics, chemistry, nanotechnology and biology.
