The current-confined-path structure consists of magnetic nano-contact in a thin insulator layer sandwiched between two magnetic layers. Under dc, in the magnetic nano-contact, motion of magnetization is driven and induces voltage noise signal with a certain characteristic microwave frequency. Interestingly, the noise has high Q-value and thereby is applicable to a microwave source for the wireless telecommunication. > For the application of the current confined path structure to the GMR element or microwave source, the control of the noise is important. We theoretically have investigated the mechanism of the noise and discussed the noise control method[1-3]. In this seminar, we introduce the investigations and future perspective of related topics. > References~ > [1] K. M. et al., Journal of the Physical Society of Japan 79 (2010) 093801~ [2] K.
