“…So far, the predominantly investigated application of YMnO 3 is the metal-ferroelectric-semiconductor field-effect-transistor (MFSFET), [19][20][21] and there are only few reports about resistive switching of both hexagonal 22 and orthorhombic 23 YMnO 3 thin films. In this work we analyze the unipolar resistive switching behavior of hexagonal YMnO 3 .…”

We report a unipolar, nonvolatile resistive switching in polycrystalline YMnO3 thin films grown by pulsed laser deposition and sandwiched between Au top and Ti/Pt bottom electrodes. The ratio of the resistance in the OFF and ON state is larger than 103. The observed phenomena can be attributed to the formation and rupture of conductive filaments within the multiferroic YMnO3 film. The generation of conductive paths under applied electric field is discussed in terms of the presence of grain boundaries and charged domain walls inherently formed in hexagonal YMnO3. Our findings suggest that engineering of the ferroelectric domains might be a promising route for designing and fabrication of novel resistive switching devices.

“…On the other hand, the mixed samples present two slope changes, leading to a maximum and a minimum in the second derivative curve. The minimum values, which are 70.9, 73.4 and 76 K for YMO_700, YMO_800 and YMO_900, respectively, are close to T N h 18,51 , while the maximum values of the curve, which are 37.8, 40.7 and 41.9 K, are close to the Néel temperature associated to the orthorhombic phase of YMO (T N o ) 24,52,53 . These features suggest a slight effect of the sintering temperature on the increase of the transition temperature for both mixed and single-phase samples.…”

Here we report on the dielectric and magnetic properties of polycrystalline samples of YMnO 3 where the ratio between both orthorhombic (o-YMO) and hexagonal (h-YMO) phases has been controlled by means of appropriate sintering treatments. Interestingly, we observe that the dielectric behavior is dominated by the presence of the metastable o-YMO phase, even though its amount remains as a minority phase. On the other hand, it also influences the magnetic behavior for sintering temperatures below 1000 ᵒC, and in addition, a weak ferromagnetic contribution is always detected in our polycrystalline samples regardless the o-YMO content.

“…However, the ferromagnetic hysteresis loop measured in YMO-LFO multilayer grown on (001)-STO should be attributed to non-canceled multi-/twin-domain structure, rather than the designed interfaces. It has been reported that YMO films with multi-/twin-domain structures show the clear ferromagnetic hysteresis loop though YMO is an antiferromagnetic compound [26]. Considering the universal existence of multi-domain structure in perovskite thin films grown on (001)-substrates, the spin-glass behavior observed in the LaFeO 3 -LaMnO 3 multilayer grown on (001)-STO substrate [10] may also come from the multi-domain structure.…”

The microstructure of multiferroic LaFeO3-YMnO3 (LFO-YMO) multilayers grown on (001)- and (111)-SrTiO3 substrates is characterized by the transmission electron microscopy (TEM). Detailed TEM characterization reveals that LFO-YMO multilayers grown on both substrates have clear layer-by-layer morphology and distinct chemical-composition layered structure. The most notable feature is that LFO-YMO multilayers grown on (001)-SrTiO3 substrate have three types of domains, while those on (111)-SrTiO3 have only one. The multi-/twin- domain structure can be qualitatively explained by the lattice mismatch in this system. The details of the domain structure of LFO-YMO multilayers are crucial to understanding their magnetic properties.
