Multiferroic properties of YCrO3 thin films on glass substrate

A comprehensive review on the ferroelectric orthochromates: Synthesis, property, and application

“…Atomic force microscopy indicated that the grain size of YCrO 3 thin films deposited on glass substrate was smaller than those on the Rh substrate. Piezoelectric force microscopy indicated that the domain structure of YCrO 3 thin films deposited on glass substrate was smaller than those on the Rh substrate, which was due to that the YCrO 3 thin films on glass substrate have a smaller domain wall energy than those on the Rh substrate [119]. The thin-film YCrO 3 samples deposited on the (111) Pt/Ta/glass substrates showed a good ferroelectricity, and the remnant polarization value was equal to ∼ 5 µC/cm 2 .…”

“…This was ascribed to the lower ferroelectric polarizations of YCrO 3 [118]. With the same method, Seo et al also deposited poly-crystalline YCrO 3 thin films on the Ta/glass/Pt substrates [119,120]. The YCrO 3 thin films deposited on glass substrate have a smaller ferroelectric polarization than those on single crystalline Rh substrate, but the ferroelectric switching speed was faster [119,120].…”

“…A hysteresis of polarization-electric (P-E) loop of the polarization curve presents at 300, 325, and 350 K [72]. Previous studies of YCrO 3 compound focused mainly on polycrystals [74,98,[100][101][102][103][104][105][106][107][108], nanocrystals [109][110][111][112][113][114][115], and thin films [72,83,86,[116][117][118][119][120][121][122][123][124][125][126][127][128][129]. The lack of high-quality and large-scale single-crystalline samples has been a long-standing issue for realizing potential applications to some extent and studying their intrinsic physical properties [130][131][132][133][134][135][136][137].…”

Crystalline and magnetic structures, magnetization, heat capacity and anisotropic magnetostriction effect in a yttrium-chromium oxide

“…Chemical substitution effect in the Y 1−x M x CrO 3 (M = Mg, Ca, Sr, Ba) compound [17] and defect chemistry of the Ca-doped YCrO 3 compound [18] were investigated. The YCrO 3 compound in forms of bulk and thin film was suggested to be a candidate material for high-temperature thermistors [19][20][21]. Among the catalysts of ABO 3 -type perovskite oxides (A = La, Y, Nd, or Gd; B = Fe, Mn, Cr, or Co) for the oxidation of 1,2-dichlorobenzene, the YCrO 3 compound was found to be the most active catalyst and was the only one that displayed no loss of its initial activity after several hours on stream [11].…”
