Non-collinear magnetic ordering may convert singlet superconducting correlations into long-range triplet correlations (LRTC). The magnetically controlled appearance of such correlation may be used to change the state of low-temperature spintronics devices. The experimental evidence of such triplet correlations was revealed by the recent observation of long-range Josephson effect. All these LRTC magnetic structures contained from 4 to 9 different layers that demand high requirements to technology and magnetic configuration controlling. Recently also spiral (or conical, like Ho) ferromagnets have been used as elements of complex multilayered magnetic structures, and the corresponding proximity effect was calculated for some configurations.
