▎ 摘　　要

NOVELTY - The device has pressure bolts (1) and a sample compartment (2). The sample compartment is open at one end and closed at the other end. An open end cavity is provided with a thread. The thread is matched with an external thread of the pressure bolt. The threaded end of the pressure bolt is screwed into the sample compartment, and a sample (4) is placed in the sample compartment. The pressing bolt and a gasket (3) is made of one of copper, silver, gold, aluminum, platinum, iron, graphene, and carbon nanotubes. A lubricant is one of graphene, graphite, alcohol, acetone, and lubricating oil. USE - device for measuring magnetism by applying uniaxial strain. ADVANTAGE - This device helps to study the effect of uniaxial pressure on the magnetism of the sample, and is of great significance for understanding the interaction mechanism of multiple order parameters in magnetic materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the application method of the device for applying uniaxial strain measurement magnetism. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for measuring magnetism by applying uniaxial strain. Pressure bolt (1) Sample compartment (2) Gasket (3) Sample (4)
