Fundamental Research on Magnetothermal Control Materials at Cryogenic Temperatures
This research aims to perform fundamental research on magnetothermal control materials in the cryogenic region below 20 K, striving to create innovative magnetic materials capable of actively or passively controlling thermal phenomena such as heat generation, heat absorption, heat flow, and heat storage (regenerative cooling) via magnetic fields. By actively leveraging quantum physical properties that emerge exclusively at cryogenic temperatures, we promote material development based on novel principles that transcend conventional paradigms. Focusing on the microscopic spin structures and phase transition phenomena of abundant elements (devoid of scarce and toxic elements), this project seamlessly conducts research from the elucidation of microscopic physical properties to the imparting of macroscopic thermal control functionalities, practical implementation into cryocoolers, and applied development toward magnetic refrigeration systems. Through this integrated approach, we establish the foundation for next-generation cryogenic magnetothermal control technology that overcomes resource risks.
