Intrinsic Disordered Network in Multiferroic YMnO₃ Single Crystals for In-Materio Physical Reservoir Computing Through Tuneable Domain-Wall Structure.

ABSTRACT: Physical reservoir computing (PRC) is an innovative computational paradigm that leverages intrinsic nonlinearity of physical systems to efficiently perform complex tasks. It is discovered that the intrinsically disordered domain structure in multiferroic YMnO₃ provides significant nonlinearity, making it a promising candidate for robust PRC with tuneability and functionality at high temperatures. This work explores the potential of YMnO₃ single crystals for PRC. PRC performance of YMnO₃ is systematically evaluated by analysing its nonlinear responses, phase shifts, and high dimensionality through benchmark tasks such as waveform generation (WG), memory capacity (MC), and second-order nonlinear autoregressive moving average (NARMA2) time-series prediction.
