A dielectric material composition including a metal oxide represented by a general
formula, Y1-xM1xMn1-yM2yOm.
M1 is Y, Ho, Er, Yb, Tm, or Lu. M2 is Ti, Zr, V, Mo, Mg,
Cu, or Zn. X is a number of 0 to 1. Y is a number of 0 to 1. The metal oxide is
of high dielectric constant and has the properties of ferroelectricity, piezoelectricity,
and pyroelectricity.
