Pressure induced enhancement of ferroelectricity in multiferroic $R$Mn${}_2$O${}_5$($R$=Tb,Dy, and Ho)

C. R. dela Cruz, B. Lorenz, Y. Y. Sun +5

Measurements of ferroelectric polarization and dielectric constant were done on $R$Mn${}_2$O${}_5$ ($R$=Tb, Dy, and Ho) with applied hydrostatic pressures of up to 18 kbar. At ambient…
