Rotation angle sample rod for electric transport measurement

Abstract

The invention discloses a rotation angle sample rod for electrical transport measurement. The rotation angle sample rod comprises an angle adjusting knob, an angle adjusting dial, a vertical sliding block, a horizontal sliding groove, an inclined sliding groove, a transmission rod and a sample table fixing shaft; the angle adjusting knob is used for manually adjusting the rotation angle of the sample rod by controlling the vertical sliding block to move; the angle adjusting dial is used for displaying the range of the knob; the horizontal sliding groove is located in the center of the verticalsliding block and used for transversely limiting a screw at the upper end of the transmission rod; the inclined sliding groove is formed in a sample rod shell and is used for longitudinally limitinga screw at the upper end of the transmission rod; a screw at the lower end of the transmission rod is connected with a sample table through a rotating shaft hole in the back surface of the sample table and is used for overturning the sample table; the sample table fixing shaft is used for fixing the sample table; and when the sample table is rotated through the sample table fixing shaft, the screwat the upper end of the transmission rod is limited at the intersection of the horizontal sliding groove and the inclined sliding groove. With the rotation angle sample rod adopted, the problem thatthe space utilization rate of an existing sample rod is insufficient is solved.

Description

technical field [0001] The invention belongs to the technical field of measurement, and more particularly relates to a corner sample rod for electric transport measurement. Background technique [0002] In recent years, exploring the material characteristics by changing the angle of the applied magnetic field has gradually become an important means to measure the electrical transport properties of topological materials. The rotation angle measurement method derived from this has opened up a new perspective for the study of various singular properties of matter under strong magnetic fields. Related topics have made great progress in the research of Fermi surface characteristics, superconductivity, and two-dimensional topological surface state behavior. Phased results. On this basis, further increasing the magnetic field strength and extending the electrical transport research of materials to the quantum limit region is an important way to discover more abundant physical phen...
