“…Since the perfect spin polarization should result in large MRR, CrO 2 can be a candidate material for the development of spintronics devices such as spin valves and magnetic random access memories (MRAMs). CrO 2 -based tunneling magneto-resistance (TMR) junctions have been studied by several kinds of barriers, such as TiO 2 [13], RuO 2 [13][14][15], SnO 2 [16], Cr 2 O 3 [17], Cr 2 O 5 [18], Fe 3 O 4 [19] and MoO 2 [20]. At 77 K and 1 T, the maximal magneto-resistance ratios (MRR's) were observed as 5~10% for most of the above systems.…”

“…By optimizing the fabrication process, TMR ratio of the MgObased MTJ can even reach 604% at room temperature [35]. In addition, other new magnetic materials are developing to enhance the performance of TMR sensors, such as Heusler alloys [40,[42][43][44][45], ferrites [46,47], rutiles [48], perovskites [49], dilute magnetic semiconductors [50], and so on.…”

Smart living is a trending lifestyle that envisions lower energy consumption, sound public services, and better quality of life for human being. The Internet of Things (IoT) is a compelling platform connecting various sensors around us to the Internet, providing great opportunities for the realization of smart living. Spintronic sensors with superb measuring ability and multiple unique advantages can be an important piece of cornerstone for IoT. In this review, we discuss successful applications of spintronic sensors in electrical current sensing, transmission and distribution lines monitoring, vehicle detection, and biodetection. Traditional monitoring systems with limited sensors and wired communication can merely collect fragmented data in the application domains. In this paper, the wireless spintronic sensor networks (WSSNs) will be proposed and illustrated to provide pervasive monitoring systems, which facilitate the intelligent surveillance and management over building, power grid, transport, and healthcare. The database of collected information will be of great use to the policy making in public services and city planning. This work provides insights for realizing smart living through the integration of IoT with spintronic sensor technology.
