摘要:
The present paper describes a loop tracer devised for ferroelectrics that can record hysteresis phenomena instantaneously. Digital technology has been applied to the conventional Sawyer–Tower circuit to provide a new system. Owing to its fast operation, it is easy to observe the loop of aged specimens without changing their electrical state, as well as to follow the depolarizing process dynamically when an ac voltage is applied.
