Caption

Time evolution of RTN signals with the corresponding RTN histograms of 1/f 2 feature in the noise power spectra at negative (a) and positive voltage (b). The high-resistance state in the 1/f2 histogram represents antiparallel spin states between layers (a) and the low-resistance state for parallel spin states between layers (b).
