The MTJ with Al-O thickness of 0.8 nm and areal size of 20μm x 20μm exhibited resistance area product RA of 6 kΩμm^2, MR ratio of 10%, and coercivity of TbFe layer of 4 kOe at a bias voltage of 40 mV. The coercivity of TbFe layer decreased down to 2 kOe at a bias voltage of 350 mV because of the Joule heat generated in the Al-O junction. From the MTJ resistance after the application of heating pulse, we measured the applied field dependence of the power density necessary for the thermally assisted magnetization switching. The power density was confirmed to increase with decreasing the applied field, and was estimated to be 80μW/μm^2 at the external field of 100 Oe. From this result, it is concluded that the MTJ with RE-TM alloy is effective for low power thermally assisted switching.", "subitem_description_language": "en", "subitem_description_type":
