Pig. 2.8. (a) Phase diagram of the field-induced spin density wave (FISDW) states predicted by the standard model. The dashed line indicates the experimentally supposed reentrance in (TMTSF)2C104. (b) Phase diagram of (TMTSF)2PFe obtained from Hall effect and magnetoresistance measurements at approximately 6kbar. Prom [79]... [Pg.20]

When large current densities (10+7 A/cm2) cross CPP spin valves, spin transfer effects start to be observed. When a spin polarized DC current flows across the CPP device, both well defined spin wave modes, and chaotic spin wave generation has been observed as a function of the injected DC current [65], These spin-wave modes lead to excess magnetic noise. These effects were first predicted by Berger [66] and Slonczewski [67], and have been now experimentally observed by several groups. At low frequencies, spin transfer effects also affect the CPP device transfer curve [68], and can be used to induce free layer switching in magnetoresistive devices. [Pg.419]
