During the last decade, current-induced magnetization switching by spin-orbit torque (SOT) is of great importance to nanoelectronics due to energy-efficient control of spintronic memory and logic devices. However, it has a problem that an external magnetic field is required to switch magnetization of a device when magnetic layers are perpendicularly magnetized. This implies that there should be limitation of scalability and low energy efficiency because of necessity to use the external magnetic field. Therefore, field-free switching of a magnetization should be achieved for realization of the energy efficient and ultra-fast SOT-driven devices.
