Magnetostimulated Chandges of Microhardness in Potassium Acid Phthalate Crystals

TL;DR

This study investigates how a magnetic field affects the microhardness of potassium acid phthalate crystals, revealing volume-related changes and potential structural rearrangements induced by magnetostimulation.

Contribution

It is the first to demonstrate a volume-character effect of magnetic fields on microhardness and discusses possible structural changes in potassium acid phthalate crystals.

Findings

Microhardness decreases by 15-18% after magnetic field application.

Microhardness in the (100) plane increases by 12-15% and then stabilizes.

Interlayer water does not cause the observed changes, serving only as an indicator.

Abstract

A decrease in microhardness along the (010) cleavage in potassium acid phthalate single crystals by 15--18% after the application of a permanent magnetic field was revealed for the first time. It is shown that the effect revealed is of the volume character. The role of interlayer water in the processes stimulated by a magnetic field is studied., Interlayer water plays does not cause the observed changes it only plays the part of an indicator of these changes in potassium acid phthalate crystals in a magnetic field. It is established that microhardness in the (100) plane of the crystal in an applied a magnetic field first increases by 12--15% and then remains constant in time within the accuracy of the experiment. The possibility of varying the crystal structure of potassium acid phthalate crystals by applying magnetic fields inducing rearrangement in the system of hydrogen bonds or in the defect structure is discussed.
