THERMAL AND ELECTRICAL-PROPERTIES OF THE NOVEL ORGANIC NONLINEAR CRYSTAL L-ARGININE PHOSPHATE MONOHYDRATE

The thermal expansion, specific heat, dielectric constant, and resistivity of the novel organic nonlinear crystal, L-arginine phosphate monohydrate have been measured as a function Of temperature. The thermal expansion is highly anisotropic and has been interpreted on the basis of crystal structure. The dielectric constant and resistivity exhibit a temperature dependence that is similar to that of an ionic crystal. No anomalies are observed in these physical properties from the liquid nitrogen temperature up to its melting point.
