• First found widespread thermal relaxation hysteresis effect in ferroelectrics

    Relaxation was first discovered in the ferroelectric common thermal hysteresis, a, background effect is reversible Carnot thermal change material under adiabatic or isothermal conditions for the magnetic field, electric field, pressure, mechanical stress and external stimuli. Recent studies have found that, in the vicinity of phase change materials discovered enormous thermal effects, phase change materials are considered solid state refrigeration to achieve clean and efficient the most promising candidates. In order to develop a solid-state phase change material for cooling, the past 20 years, people use of direct and indirect methods of thermal effects tephigram adiabatic temperature change and change, etc. intensive studies. However, the material Another important parameter –
